The demand of the modern-day market is pushing developers and business owners towards better and faster solutions. Companies and are looking to streamline their workflow, and the launch of their respective products and software. In the current technological landscape, application development is getting a powerful boost thanks to the cloud. For most of these companies, refactoring legacy applications is already a familiar occurrence and a necessary step forward.
What is Refactoring?
Refactoring legacy applications is quite simply a natural part of any application development. It is a process that will happen sooner or later. The key thing is being ready to make the move and knowing what’s best for your business when it comes to cloud adoption and cloud migration.
With refactoring you ensure technical debt is kept to an acceptable level. An application will be refactored many times during its lifecycle, thus adding new features and functionality. The goal is refactoring an application to enable components, or all of its features to run on public cloud services.
The challenge is having legacy applications that are mandatory for your business in order to operate, and usually this is not designed for a cloud-based approach – that’s when the process of refactoring jumps in. Rearchitecting or rebuilding can kick off as soon as existing architecture is determined and mapped out.
Making Things More Efficient and Future-Proof
When talking about the mechanics of it, and the basics of refactoring and restructuring code, there are other things to consider. For example, if you got large elements of the application that can have their components separated into external services – in this instance, sort of a hybrid approach that occurs with the cloud migration process. This entails, as we’ve mentioned earlier, preserving essential elements of the existing app as is and moving out parts of the app to utilize within cloud native services.
Improving Agility to Suit Enterprise-level
This is where things get interesting. With this move you’re essentially leveraging the development investment from the public cloud providers, who spend billions to make your business operations cheaper and easier. As a result, you are reducing your overheads, which is one massive benefit. If you have a legacy app or elements of your business on an enterprise scale that is causing you headaches and you constantly have to micromanage it and monitor it, the obvious solution is to use cloud native services instead, therefore giving yourself some time to focus on your core business. That’s another huge benefit. If DevOps isn’t the core of your business, then cloud services will handle that for you.
Utilizing Ephemeral Computing
As of late, we have seen a powerful push towards serverless and a huge part of this is relying on ephemeral computing processes. An increasing amount of businesses are steering their operations towards the pay-as-you-go model. More importantly, we’ve also seen the implementation and use of grid computing and ephemeral computing, both of which are already a vital component in modern-day handling of business workloads.
Serverless Application Refactoring
In this particular instance, we are referring to removing a virtual machine or server where something is hosted and deployed to. In Hentsu we are constantly using the strength of the public cloud to carry this out internally, while relying on powerful tooling such as Azure App Service, AWS Lambda, and AWS/Azure Batch. We also offer huge amounts of vertical and horizontal scaling these services are pay-as-you-go, which allows you to turn the services off and reduce your costs to zero; something that is impossible with private cloud. This is a benefit to both our operations and to what clients require for their own workloads.
There are other numerous advantages that come with the serverless solution. You can check these out below:
- Cloud native serverless solution unlocks massive processing power when needed.
- You pay only for what you’re using.
- Integrated multi-region resiliency across the public cloud.
- In that environment, you can utilize auto-scalability based on workloads and user demand.
- Integrated alerts, health checks, automated recovery and restarts if any service fails.
When we’re talking serverless computing, we need to understand what this involves. The main facet of serverless is the power to abstract the servers, infrastructure, and operating systems, and that allows developers to devote their attention to application development.
Beyond that, you also have the opportunity to power everything with code and with the help of Azure cloud you are laying a solid foundation for a smooth DevOps environment. In relation to that, companies can make use of Continuous Integration/Continuous Delivery (CI/CD) of applications to launch fully tested and integrated software versions minutes after development.
