Cloud Computing Basics - What Every User Needs To Know About Their Cloud App

Cloud Computing Basics - What Every User Needs To Know About Their Cloud App

As more and more applications begin to leverage the cloud as a major part of their architecture, it makes sense to take a step back and understand just what is going on in terms of cloud computing basics. Much of the cloud is abstracted away from both the app developer and especially the end user. But it is a good idea to explore exactly which services the cloud is providing and how. Here is what every user needs to know about their cloud app.

Building Your App Is Much Easier

When you use cloud services, your app automatically becomes easier to build and maintain. Why? Because pre-built services mean you have less code to not only write but also less code to test. Cloud services tend to be mature and robust offering good documentation as well as error handling and a standardized interface. These are the things in life developers tend to struggle with or don’t enjoy doing.

Having the ability to pick and choose best of breed cloud services, your app becomes less of a monolith and more flexible, giving you the ability to change things around without having to re-work or write new code. You can get more accomplished in a shorter period of time, something IT managers will praise you for.

Testing Your Application Is Faster

With the ability to spin up a virtual testing infrastructure in the cloud literally in minutes, you gain a tremendous advantage in testing speed. Moving code through the various testing environments is no longer a tedious and burdensome task that requires three or four people to validate. You simply create (provision) what you need from pre-configured templates using cloud infrastructure management tools and voila, instant infrastructure and near-instant testing.

Once your testing infrastructure is set up and you have your testing process honed in, future testing becomes almost a joy since all the baggage that comes along with a traditional environment is gone. You can get something into the end user’s hands quickly and be able to validate requirements, functions and features more efficiently.

Your App Becomes Location Aware

One of the benefits of using cloud infrastructure is that the app’s static files like images, JavaScript files and CSS files can be served to the end user from the closest server location to the end user. This is called a Content Delivery Network (CDN) service where the location of the user is computed and provided to the CDN service. The service then finds a server closest to the user’s location and serves the file from there.

Why is this important? The Internet has no set route that data is transferred by. It does its best to route traffic in the most efficient manner possible but sometimes it’s not the fastest route. Using a CDN ensures that the best opportunity for data to travel the least distance and therefore arrive faster is achieved. Your app appears faster and more responsive to your end users.

Your App Requires Careful Attention to Security

By moving to the cloud, it is imperative that you know exactly how the cloud provider handles security, both physically and with data. Using storage services is one thing, but knowing how the data is stored and what steps are taken to ensure ongoing access integrity is paramount. If your app stores and retrieves sensitive data using cloud services, then your app must take additional measures to secure transporting and storage of the data.

Your App Relies Heavily on an Internet Connection

Building an application that consumes cloud resources over the Internet means your app is dead in the water without an Internet connection. This may seem obvious but many apps don’t degrade gracefully when a connection becomes unavailable. The app simply times out without allowing the user to do anything else.

If your app is mission critical, it should allow for reduced functionality when a connection is unavailable and sync back up with the cloud when the connectivity is restored. This way, your users can still be productive and you don’t look like a buffoon even though it’s not your fault.

But Wait. There’s More.

Now that you know cloud computing basics, you know that cloud computing is just a fancy term for using someone else’s computing resources. With the future evolution of the Internet is leaning heavily on cloud computing, you must take a step back and take in just what this means. The way apps are built is changing rapidly and forever. The more you know about how your future as an app developer will change, the better you can be at meeting ever-changing business demands.

Six Great Lies App Developers Tell Online Marketing Managers

Six Great Lies App Developers Tell Online Marketing Managers

Online marketing managers put a lot of trust and faith in those who make it possible to do business online. Without web applications, there would be nothing online to market save for the plethora of awful affiliate marketing scams that clog the Interwebs these days. Many marketing campaigns start off with grandiose promises of instant wealth which often fail. Why? Because sometimes web app developers tell little white lies that online marketing managers blindly trust. What are these lies?

Lie #1- I Don't Know Anything About Marketing

Perhaps the biggest lie told by web app developers is that they tell marketing managers that they don’t know anything about marketing. While this may be true on the face of it, developers often think that marketing isn’t that hard, certainly not any more difficult than the complex work they are doing.

Since developers design and implement their apps to reach a certain audience, they think marketing is something they can just “build in” to their app and they tell marketing managers that all the promotion functions they need are built right in. But how would they know?

Lie #2 – It's Easier to Start From Scratch

When marketing comes up with the next big idea for their online strategy, they want it implemented quickly and as cheap as possible. To make this happen, a web app developer will sometimes tell marketing that it will be easier to start from scratch rather than try and retrofit new features in an existing web app. It might be quicker but it is rarely cheaper.

This lie is merely a façade to mask the fact that the current app wasn’t written in a way that is easily extendable and the developer doesn’t want management to know about it. Instead, the developer will say that if they build it from scratch, it will use the latest technology so future changes will be much easier. However this is usually just an excuse to play with the latest and greatest development tools.

Lie #3 – Features for No Reason

When a marketing manager asks why there are certain features in their new product that weren’t on the feature list, a developer tells an innocent lie that since our competition has it, so must we. I’m just looking out for you guys long-term he says.

What he really means is that he can’t understand why marketing didn’t come up with these extra features during their competitive research. Because he is smarter than a marketing manager, he feels the need to right this wrong and put in the features anyway.

Lie #4 – The App Will Handle Huge Traffic

Every online marketing campaign has one goal in mind: drive traffic to the website and once they are there, funnel them down the desired path and make them into a customer. A successful campaign can tax even the most scalable infrastructure so designing an app to hold up is paramount.

Asking a developer if their app will handle the predicted traffic spike is like asking your wife if the pants she is wearing make her butt look big. Of course you are going to say no, else reap the wrath. And so it is true for a developer. He will say of course my app will hold up. I spent a lot of time designing it for just that reason. Chances are that little consideration was given to how scalable the app really is.

Lie #5 – My App Works in Every Browser

Online marketing managers want to reach the widest audience possible and therefore their web application must be compatible with the broadest range of web browsers that is feasible. The look, feel and speed should be the same for every user experience regardless of browser version.

When asked by marketing what browsers are supported, often a web developer will respond by saying something like all those that matter. This is a catch-all lie that really means they don’t really know since they haven’t tested on all browsers. Every developer has their favorite browser and is biased toward its capabilities. As such, it is the version that is recommended and others are merely broken.

Lie #6 – We Don't Need Documentation

Before going live with a website, online marketing managers should be trained on the web apps they intend to promote so they have an inkling of what their customers will see. Usually with a training guide or basic documentation will suffice but often it never gets written.

Documentation is the bane of all web developers. They hate doing it and think it’s a waste of time. They will say that the code is well documented and that if anyone needs to know how something works, they will show you how. In reality, no documentation exists, especially a training guide. While not typically a developer’s job, training docs can only be written effectively if a developer works with marketing from the beginning.

Conclusion

While developers tell little white lies typically to justify the presence of a bug or the absence of some feature or function, they are likely not being malicious or intentionally deceiving. They are probably just framing the lie to online marketing managers so they gain their confidence. As with any lie, white or otherwise, they always comes back to haunt you. But in this case it’s the customer that eventually suffers.

How to Test Your Website So That Your Customers Don't Break It

How to Test Your Website So That Your Customers Don't Break It

Introduction

The last thing you need is to have your website break in the first few hours of high-profile launch. Your customers are relying on you to make their experience using your website a memorable one — one they won’t forget, one that keeps them coming back for more. But if the website breaks, they will remember only the failure and likely won’t be using your website again. How can you avoid this? Test your website thoroughly so your customers don’t break it for you.

Step 1: Create the Test Plan

Begin with a test plan that covers the basic test coverage areas of requirements testing, unit testing, functional testing, system testing, user testing, security testing and performance testing. These test types may be called different things by different IT departments but the end result is that should you have end-to-end coverage that is both measurable and repeatable in the event you have several test cycles.

Step 2: Choose a Testing Tool

The testing tool you choose will have a big impact on how you test your website. Depending on the size and scale of your website, you should carefully consider a tool that will grow with the complexity of your website ecology. The goal is to have total test coverage that doesn’t hinder the pace of development but also is formal enough to integrate into development tools and workflow, i.e. bug fixes and reporting.

There are numerous test automation tools, both open source and commercial. Arguments for each abound but the bottom line is that you should choose a testing tool that fits into your IT website development tool’s long range strategy as well as the skill level of the testers.

Step 3: Test Early, Test Often

A website is tested much differently than a desktop application. A typical desktop application will have a predictable level of usage such as fat client like Microsoft Outlook in a corporate setting. A website is quite the opposite with sporadic usage with occasional spikes in traffic. This is where the architecture and design must be validated to determine if it can scale to meet demand.

Prototyping, unit and performance testing part of the website that will see the most use will provide early indications of scalability and thus the ability to re-design if performance standards fail to be met. Better to find out during the foundational design rather than at launch.

Step 4: Bake in Quality Testing

Often, quality testing is the first thing to get whacked from a project in order to save time yet there always seems to be time after launch to fix your broken website. Why not just bake in the needed time to QA test at the beginning of the project?

During this step, begin building reusable scripts with your testing tools that help you test components and modules in a repeatable way. Record quality metrics such as input validation requirements, error messages, input field order, workflow ordering, etc. This will help you build up a test suite so as the website becomes more complete, you can easily test new functions along with finished ones to see how they work together.

Step 5: Help Your Users During Functional Testing

Many websites are functionally tested by simply handing the website over to a group of users who are asked to “just do a run through and see how it works.” Save that for user acceptance testing. It is not enough to toss the app “over the fence” and see what gets tossed back.

Functional testing ensures that every functional requirement is tested according to specification, both independently and as a collection in the case of a workflow. You can dramatically improve the quality of your website by taking an active role in functional testing. As a web developer, you know best how a function was implemented. Work with your users to ensure it’s what they are expecting and solicit feedback.

Step 5: Conduct a System Test

Once the website is far enough along that all the major components have been through a functional and quality test, it’s time for a system test, which often includes a performance test. Why? Because not only are you testing to ensure each component in the website infrastructure is working in unison properly, but also to determine how the website will behave under various conditions, such as spikes in usage.

This is where your testing tools will help you tremendously. Create scripts that will run your website through all sorts of usage scenarios, from random usage to highly concurrent users working the most often used parts of the website. Measure and record baselines so you have a benchmark for follow-on testing and tuning.

Step 6: Conduct a Security Test

This step is often skipped because there is reliance on the website developer to provide security measures in their code. But that is only half of the picture. While in-code measures are implemented, unforeseen vulnerabilities can only be uncovered through penetration testing, a test that attempts to discover vulnerable parts of the website and then exploit them, rendering the website unusable or to expose data.

If your website collects or processes sensitive information, you cannot skip this step. Your customers rely on you to secure their personal information. Grave consequences are a given if there is a breach because of a website security hole. Perform the test in an environment as close to the production configuration as possible. This means firewalls, HTTPS certificates, user permissions, etc.

Step 7: Perform a Production Validation Test

This step is where your users can help greatly. After the website is launched, solicit feedback from your users. Offer them some gizmo or gadget for their time. Also monitor the website continuously for the first 30 days of usage so you can baseline usage for later tuning.

Conclusion

While these steps are not a one-size-fits-all for every website you build, it does represent a typical approach taken for testing medium to large scale websites where quality and performance are woven into the fabric of the software development process. If you only use just a fraction of what is outlined here, you will be much further along than most. And you will have fewer customers complaining about a broken website.

Little Known Ways to Make Your Website Load Faster

Little Known Ways to Make Your Website Load Faster

Website load times are the key factor in how visitors form a first opinion of your website. And now since the recent revamp of Google’s indexing and ranking algorithms, it’s imperative that your website load as fast as possible. Slow websites translate eventually to lower search engine rankings, something that is hard to reverse in a short time. When every click counts, you need ways to make your website load faster so your visitors are happy and your ranking improves. If your website is slow to load, here’s how to fix it.

Speed Secret #1 – Reduce HTTP Requests

The single most important factor in page load times (aside from a long running query) is the number of HTTP requests that are made when a first time visitor goes to your website. HTTP requests are made for resources such as CSS files, JavaScript files and images. If you have many of these resources on your main landing page and your visitor is new, the browser has yet to cache such resources which results in a longer wait time for your first time visitor. Not the impression you want to make.

You can do one of two things: simplify the page or combine resources to reduce requests. When simplifying the page isn’t an option, consider combining CSS files in to one single file. You can also minify CSS files, a technique that removes unnecessary characters from the source file so the CSS files download more quickly. This works the same for JavaScript files as well. Combining and minifying can reduced download times significantly and the busier your website, the more benefit you will reap.

Speed Secret #2 – Order Your CSS Files Ahead of JavaScript Files

A little known secret to improve overall page download speed is to place all CSS file requests ahead of JavaScript file requests in the head portion of your page. The reason is that CSS files can be downloaded in parallel but if a script file is thrown into the middle of a set of CSS files, the browser has to wait until the script file is downloaded and executed before continuing to download CSS files in parallel.

Every script file downloaded has to be executed sequentially, which means certain portions of your page may not render until the script load and execution completes as there is no style instructions to render the page yet. This is also true for inline script as well. If possible, try and put all scripts (including inline) after all CSS files in the head portion of your page.

Speed Secret #3 – Use Gzip or Deflate to Compress Pages

To save bandwidth and therefore improve page download speed, you can configure your web server to compress content requested before it is sent to the web browser. This is possible by using server-side modules such as Gzip or Deflate. Content such as CSS and JavaScript files usually contain a lot of whitespace so compressing them before download can save a significant amount of bandwidth.

If your web server is Apache 2.0 or greater, then enabling the mod_deflate module in Apache’s http.conf file will result in Apache compressing content when requested to do so by the browser. All modern browsers will automatically send a content compression request in the header of the HTTP request. If the server is configured for it, compression happens on the fly. This is true for any web server with Gzip or Deflate enabled.

Speed Secret #4 – Use a Content Delivery Network (CDN)

A CDN is a way to spread out resource requests over a number of host names and serve them up from the closest server to the requester. Web browsers are limited to the number of parallel connections to any one hostname at a time. Remember that downloading resources in parallel increases page load speed as in the case of CSS files. So to get around the parallel connection limitation, using multiple file servers with different hostnames helps a browser use more parallel connections.

CDN providers such as Amazon’s CloudFront, provide the infrastructure and simple tools to help you serve content from servers around the world. Once configured, you replace the URL to your server that would normally be used for say an image or script file and replace it with a unique URL of the CDN provider. That’s it. Instant CDN and browsers can now take advantage of parallel downloads from multiple servers.

Speed Secret #5 – Reduce the Number of Queries to Render a Page

When you have exhausted all other approaches and your site still loads slower than you would like, it’s time to look at how the database is queried. No matter how tuned up your queries are, on a busy website with a lot of queries performed to render pages, it’s going to result in progressively slower load times.

A little known technique is to combine queries where possible. Combining means taking several queries required for generating page content and making a single query that generates all page data needed, eliminating multiple queries that result in the same information collectively. Sometimes this isn’t possible when different portions of the page have completely unrelated data. Think about where you can combine queries and you will notice a substantially faster page load time and a less resource hungry database.

Conclusion

While not an exhaustive list of page loading speed secrets, following these suggestions will absolutely result in faster load times. Other areas to look at are combining images using CSS sprites, minimizing URL redirects, minimizing DNS lookups and hosting provider bandwidth limitations. Infrastructure plays a huge role in page generation and serving speed so if you have a friend in the infrastructure department, pay him a visit and work together to optimize your website.

Local Online Marketing Checklist

Marketing for local businesses has come a long way. Just 20 years ago, "marketing" meant buying newspaper ads, Yellowpage ads or perhaps billboard or radio advertisements. Marketing was costly and often ineffective.

Today, the game has changed. There are literally dozens of tools available to the smart business owner for local online marketing. Many of these tools and techniques can drive hundreds of paying customers to your business, without costing you a single dime.

This local online marketing checklist will help you get the most out of all the tools, technologies and techniques available today.

Step 1: Get on Facebook Places

Facebook places allows users to find you through their friends' check-ins. People who like your business can "like" your page or comment on your page and their friends can see that on their walls.

It's a powerful way of spreading a great business virally. It uses the inter-connectivity of Facebook to a local business' advantage.

Make sure you claim your business so you have the ability to change its information, as well as merge the Facebook Place with the Facebook Page.

Step 2: Get on Google Places

There are many great reasons to get on Google Places.

First, your business will show up ahead of other non-local businesses in the search engines.

Second, people will be able to leave reviews for your physical business.

Third, people will be able to find your place on Google Maps. For example, a user with an iPhone might type in "chiropractor" into Google Maps to find all the chiropractors near them. If you're listed on Google Places, your restaurant will show up.

Step 3: Get on Yelp

Yelp is a user-driven review site with a very active community. People who visit local businesses use Yelp to leave reviews of their experience. Other people who are thinking of going there can use Yelp to see previous reviews.

Yelp is extremely popular in some cities, like San Francisco and New York, while virtually unnoticed in others.

If you're in a city with a strong Yelp user base, getting to the first 3 or 5 results in Yelp can bring you a huge influx of customers. Many small businesses are packed every day purely from Yelp traffic.

Step 4: Give Incentive to Review

You're much more likely to get a lot of reviews if you help the process along by providing a few incentives. That's especially true if your business is relatively new.

Keep in mind that you can't incentivize others to post a good or positive review. You can only incentivize them to post a review. What they say is up to them. They should get the reward either way.

Naturally, if you provide a great service, most reviews you get will be positive.

What are some examples of ways to incentivize reviews?

• First 10 Yelp reviews gets 50% off their next meal.
• First 10 Google reviews gets a free coffee.
• People who have posted a review for our service get 10% off all purchases.
• Etc

Step 5: Host a Meetup

Meetup.com is designed to help bring people with similar interests together. It's an online site with an offline focus.

One great way to bring more people to your venue is to host an event. The event can be related to what you do, or it can be one or two steps removed. Here are a few examples:

• A co-working space – Monthly talks on marketing for small business.
• Classy café – Monthly philosophy discussion group.
• Dance studio – A free monthly "open floor" dance event.
• Rock climbing gym – Free "intro to rock climbing" event.
• Bookstore – Monthly book signings.

The list goes on and on. Talk to your customers and find out what they're interested in. Then create a meetup to cater to that interest.

Step 6: Open Your Space to Other Organizers

If you browse through Craigslist events, Meetup events or other events sites, you'll find that 5 to 10 event venues tend to be used over and over again in any given city.

You can bring in a lot of business by opening your space to other organizers.

For example, let's say a restaurant makes its back room available to a Toastmasters meeting (a public speaking group.) They use the back room free of charge, and most members end up ordering food and drink anyway.

The restaurant profits from the food and drink and gets the benefit of being exposed to a whole new audience. The back room probably wouldn't have been regularly booked out anyway, so there's no real cost to the restaurant.

Another example might be a shared co-working office. It allows its members to use the conference space for educational events free of charge, provided that all its members can also attend free of charge.

The organizer gets the benefit of having a professional space for free. The shared office space gets the benefit of having more to offer its members. Furthermore, every person who attends that event is a potential customer.

It's much more efficient to open your space up to many event organizers rather than try to organize many events yourself. Doing so can bring in a lot of new people to your business, as well as build general goodwill in your community.

Step 7: Market on Local Mailing Lists

In any moderate to large city, there will be dozens of mailing lists on a variety of different topics.

For example, in San Francisco, there are lists for hikers and runners to meetup, lists for announcements of art events, lists specifically for the yoga & meditation communities, lists specifically for the startup business community, and so on.

Make an effort to ask the people in your target audience what kind of email lists they subscribe to. Write these down and do some research.

Some lists will have "open announcement" policies, meaning anyone can post to the list. Others are curated lists, where events are sent to a single curator who posts approved events all to the lists.

Some lists will have very stringent requirements on what it's okay to post and what it's not. Others will be rather lax.

Try to find as many large, active lists in your community as you can. Market to the lists anytime you have something significant to announce. Avoid burning out the list by over-emailing; but use the power of pre-existing communities to your advantage whenever you're doing a special promotion or event.

Step 8: Get a Booth at Events

In-person events allow you to market your products directly to your ideal audience, while building connection and rapport through face-to-face interactions.

An "event" can be as sophisticated as a trade show, conference or seminar. Or it could be as simple as a college fair or farmer's market.

The specific events you choose depends on what market you're in. If you run a temp agency, you'll probably want a booth at college job fairs and at trade shows (to find employers.)

If you run a small, organic restaurant, you might want to get a booth at your local farmer's market and appear at all the "for fun" fairs around. (E.g. The local renaissance fair.)

Step 9: "Flyering" and Other Local Marketing

Leaving flyers at local businesses, putting flyers on walls, putting door hangers and perhaps even mailing postcards all still work. Just because a tactic is old doesn’t mean it's no longer effective.

When using these tactics, the most important thing is to make sure you're reaching the right people. If you're promoting a nightlife event, flyer outside nightlife venues. Don't leave your flyers in restaurants.

Step 10: Negotiate with Groupon or LivingSocial

Groupon, LivingSocial and other group-buying organizations can bring you a lot of business. In fact, it can bring you hundreds of orders in a 48 hour period.

Generally these sites will want to only work with established businesses. They need to know that you can handle the sudden volume that they'll send you.

They also need to know that you'll be able to give their users a significant discount, while still paying them a percentage.

Let's say you run a health and massage spa center. The standard price for a massage is $90, but for Groupon members you're offering it for $55. In addition, you need to pay Groupon $5 per sale.

If you're hiring your masseuses' for $60 an hour, you're essentially breaking even. If you're paying them $65 an hour, you're losing money. You need to know that even if you spend $5 to get someone through the door, you'll still make money in the long run.

In other words, Groupon is such a high volume business that it takes experience, knowledge of your customer behavior and strong financial muscle before you can work with them.

All that said though, if you can get your business to meet their standards and criteria, the amount of sales you can get from Groupon or LivingSocial is simply astounding.

These are some of the most powerful methods available for marketing an offline business today. Try to apply as many of these tactics as possible, identity the ones that work best for your business, then rinse and repeat.
