Application Modernization is an inevitable and necessary part of a cloud-first digital transformation. Application modernization consists of creating a project that is designed to produce new business value from existing legacy software, while updating the existing structure with modern features and capabilities. When modernizing and deploying with AWS, enterprises can reduce payback periods to 6 months and reduce total cost of ownership (TCO) by 64%.
Before your organization can begin its modernization journey, it’s important to evaluate if it’s a viable solution for your business. Learn more about application modernization by reading our previous blog on “How to Modernize Legacy Applications” here.
EagleDream uses multiple approaches to building modern cloud-native solutions. In the following post, we will outline what is involved in each and how they can contribute to overall improvements in scalability, reliability, and cost efficiency.
The 3 Approaches to Modernizing Legacy Applications
There are three main approaches that EagleDream is taking in helping enterprises “be cloud-native:” Serverless, Containerization, and Cloud-Native Replatforming. Each approach uses distinct methodologies; therefore, catering to specific use cases. Determining which approach is right for you is one of the first steps to embracing modernization:
Serverless enables your organization to shift more of your operational responsibilities to the cloud without relying on a server, increasing your agility and innovation. This allows you to build and run applications and services by eliminating infrastructure management tasks such as server or cluster provisioning, patching, operating system maintenance, and capacity provisioning.
Building serverless architectures allows developers to focus on their core product instead of the worries of managing and operating servers or runtimes. With this reduction in overhead, developers can save time and energy, while working in the cloud or on-premises. Other benefits include:
Containers provide a standard way to package and deploy your application’s code, configurations, and dependencies into a single object. This allows software to run reliably when moved from one computing environment to another. Some of the most common use cases for containers include building and deploying microservices, running batch jobs for machine learning applications, and moving existing applications into the cloud. Benefits of leveraging containers can include:
3. Cloud-Native Replatforming
The replatforming approach consists of moving applications almost “as-is,” while replacing some components to take advantage of the cloud. Common modifications include transforming the way a program interacts with the database to benefit from automation or enabling better scaling and utilizing reserved resources in the cloud environment. This approach allows developers to reuse the resources they are accustomed to working with such as development frameworks or legacy programming languages. Other benefits of replatforming include:
How Do I decide between using Serverless vs. Containers?
Although serverless and containerization do have some similarities, both are used for different cases. Serverless is a more viable solution for your organization to execute resource-intensive code on a one-off basis and if traffic pattern changes need to be automatically detected and handled instantly without second-guessing the ability to scale. With serverless, applications are only running when there is traffic, so your business will only be paying for the resources you use.
Containers are more suitable if you need the flexibility to install and use software with specific version requirements. With containers, you have full control of the installed programming language and runtime version. This allows applications to be moved quickly between host servers and becomes extremely useful for migrating legacy applications to the cloud because it enables developers to replicate the applications original running environment.
How has COVID-19 Accelerated Application Modernization?
During the months of March through May, recent data shows that organizations have accelerated in moving towards consumer and business digital adoption in a matter of eight weeks. With that being said, the data has also indicated that prior to the COVID-19 hit, 92 percent of companies thought their business models would need to change given digitization.
Although the need for modernizing applications isn’t a new concept, businesses are rushing to keep up with the radical and unpredictable changes created by the current COVID-19 pandemic. With an adjustment in consumer needs and expectations due to social-distancing, companies are looking for new ways to find resilient and cost-effective software systems with few external dependencies like on-premise work collaboration or hardware resources.
