Application Testing in the Cloud


Tagged: , , , , ,

If you’ve been keeping up with the hype, you’ve probably been looking into deploying a cloud of some form in your organisation. Be it public, private or hybrid cloud, the possibilities that they come with are endless and revolutionary. I’m sure you’ve heard all of those buzzwords before, building the idea of ‘the cloud’ into an amazing, it’ll-fix-any-problem-you’ve-ever-had-and-more! miracle that’s more of a unicorn than anything else. But you might have discovered that it’s not all sunshine and rainbows when it comes to cloud. Application testing has become one of the little bugbears that people forget- or choose to ignore- when putting together a cloud strategy. When you roll out anything new, it’s important that it’s a success- your bottom line could very well depend on it. And without regular testing you don’t even know what you’re throwing out into the world.

Several years ago, virtualisation became a new focus for IT departments. This new ideology of sharing computing resources across multiple operating systems increased productivity through reduced costs and increased scalability and easy administration. This fabulous new way of running IT infrastructure observed the evolution of virtualisation of cloud in the form of cloud computing. It paved the way for the dream of ‘Everything as a Service’, essentially creating a foundation for many of the technological advances we have today (but for some reason I still can’t get a delivery from the McDonalds a mile away, so there are clearly more worldly advances yet to be achieved).

Cloud testing is the actual testing of the resources on demand; think hardware, software etc. Testing is crucial for the health of your IT environment, especially when it comes to your cloud offerings, ensuring that it not only meets functional requirements, but also non-functional. Securing and managing performance of your applications is essential regardless of where they are; in the cloud or on-premises. It’s not the case of testing an application when it first gets deployed and never needing to bother with it again; the status of applications can change over time.

There are so many benefits for cloud testing that are easily obvious when you experience them. The normal testing approach is to invest in the adequate hardware and software infrastructure needed to carry out the testing. Since the environment supplied to the testing team very rarely matches that of the user, testing applications in the cloud can alleviate the issue of rapidly-changing requirements, allowing the tester to easily replicate the user environment and find defects early in the cycle. Migrating apps to the cloud can also reduce the cost of infrastructure licence renewal, as the organisation doesn’t have to purchase the infrastructure that won’t all be in use at the same time. With the end user environment in the cloud, it’s a simple enough task for an IT department to customise the testing environment match. This customisation reduces the cost and time of regular testing. The testing team can easily perform load and performance testing scenarios in various permutations and combinations.

But, as with everything, there are downfalls. I hate to have to list them, but here we are. By relying on and using the cloud as infrastructure, we do face a few hiccups. But nothing too scary, I promise. Security is one; user privacy needs to be protected, while also allowing the necessary protections that hold up to standards. The security of applications that run in the cloud and security testing techniques also need to be addressed by organisations when it comes to cloud infrastructure. The performance of an application in the cloud is another significant issue that regularly gets overlooked. How are we to know if an application works the same way, especially when hosted in a private cloud? The application itself will be shared amongst plenty of users, so that could cause a delay, especially if bandwidth isn’t good enough for testing. It’s surprising that in certain instances, the particular configurations of a user can be that complex that they just simply aren’t supported by that cloud provider. I don’t get it either. Bottom line, that can make it that much more difficult to emulate a user environment. The last little issue is that of integration testing. It’s easy enough to test the network, database, servers, and whatever else needs to be done. The tester already won’t have control over the underlying environment, but on top of that they’ll have to essentially guess how it would behave. If there are interactions between two components, the tester can only anticipate risks, such as crashes, network breakdown, or your server going on a sudden holiday.

Ensuring the maintenance and performance of your applications in your chosen cloud is crucial for your organisation. Where a lot of people would just love to ignore the finicky bits of testing, here at Cetus we like to dot the Is and cross the Ts, and that includes your testing. Our experts are specialists in application testing and making sure that everything works just right. If testing of your applications is something you’d like to master, make sure to have a chat with one of our experts who will show you first-hand the benefits, while eliminating as many downfalls as possible.
