Clearly defined needs, speed and excellent knowledge of the Cloud area – that’s what it took to move the client’s infrastructure to the cloud and reduce the time needed to deploy new application versions by 50%. How we did it and what were the results of following the SlickCloud path? Read the following case study and see that in our case, effectiveness is not an empty phrase.

Problem: inefficient application

The CEO of a software company approached us with a clear need – we were to streamline the deployment of their application in AWS and create pipelines in GitLab CI/CD. In this case, the preparation did not take long. In fact, the biggest challenge at the beginning was to analyze the client’s infrastructure. The next step we had to take was to create a migration plan that allowed us to go through the process quickly and efficiently.

The challenge: maximum efficiency without downtime

Although the task itself seems easy, in fact it is not. To streamline the application deployment in AWS, we first had to achieve the most important goal – to migrate the application to the public cloud. The client was using an on-premise infrastructure that was running production applications. This means that the goal was not only to move applications to AWS, but also to make the most of the opportunities offered by the public cloud. And how to do it without disrupting the company’s business? This is not the first time that we have faced such a challenge. Here’s how we handled it.

The solution: a simple way for SlickCloud to migrate infrastructure

The most important and also the most sensitive part of the whole system was the database, which had to be constantly available during our work. To migrate it to the AWS public cloud without downtime, we used AWS Database Migration Service, a service that allows real-time replication of data between the old database in the on-premise environment and the new one in AWS. This allowed us to migrate the application without affecting its performance in the production environment.

Although the task was challenging, it did not cause us any problems. After all, migrating to the cloud is our standard fare. Our AWS cloud experts used their experience from previous projects and planned the migration according to best practices.

Effects: reliable and safe application

The SlickCloud path we developed over the years led us straight to the point. We successfully moved the application to the cloud, but our client was most interested in the results of this operation. Because of the work we have done the application mentioned can now be scaled more easily, and increased reliability of its operation (high availability) can be ensured. This, coupled with the introduction of CI/CD, has reduced the time-to-market of the application, and significantly increased developer productivity. In addition, we have reduced the risk of potential bugs in the application itself and ensured its security improved when compared to the on-premise environment.

SlickCloud’s success in numbers

The effects described above are not the end of our successes in this project. Because of the changes we have made:

  • the time to introduce new features and fixes to the application has been reduced by about 50%,
  • developers’ productivity increased by about 25%,
  • we achieved application availability of 99.99%.

 

How was the cooperation evaluated by the client?

You already know what results the client’s company saw after our intervention. And what did its CEO say about the cooperation? See below.

“What really set SlickCloud apart was their commitment to understanding our specific needs and challenges. They did not offer a one-size-fits-all solution, but tailored their expertise to our unique project requirements. Their in-depth knowledge of AWS and GitLab was evident at every stage of the project.”
