Application Modernization and 6 R’s

Enhanced functionality, rapid innovation, increased efficiency, reduced operating and infrastructure costs, more scalability, improved overall experience, flexibility… It’s like opening a door to unlimited possibilities with the cloud.

Moving your business applications to the cloud has many advantages, including those described above. The problem is that many companies don’t realize that taking advantage of the benefits of the cloud requires little more than just porting an app.

Most legacy software is based on a single database with a monolithic architecture with very narrow scope for on-demand scalability, rapid development, high availability, etc. Despite the simplicity of this technique, it has significant limitations in terms of size, complexity, continuous deployment, start time, and scaling up.

What is app update?

Updating an application is the process of updating it with the latest technologies, such as the latest programming languages, frameworks, and infrastructure. This process is referred to as “updating legacy” or “updating legacy apps.” Making improvements to efficiency, security, and structural integrity is like remodeling an old home. As an alternative to replacing or terminating an existing system, application update extends the life cycle of an enterprise software while taking advantage of new technology.

Why do companies need to update apps?

By implementing an application update, the company maintains its existing investment in software while taking advantage of the latest developments in infrastructure, tools, languages, and other technical aspects. The application update plan reduces the resources required to run the application by implementing a modern approach. It improves deployment frequency, reliability, uptime and resiliency among other things and thus becomes essential for any digital transformation strategy.

Most companies have made significant financial and operational investments in their existing portfolio of applications. “Legacy” has a negative connotation in software but is one of the most important business applications. Nobody wants to get rid of these apps and start over because of their high costs, productivity losses, and other issues. Therefore, it makes sense for many companies to update their existing applications with newer software platforms, tools, structures, and libraries.

Old update trends

Multicloud and hybrid cloud are two of the most important trends in modernizing legacy applications. Multiple public cloud services can be used for cost savings, flexibility, and other reasons. On-premises and public and private cloud infrastructure are included in the hybrid cloud model.

Rather than requiring software teams to rewrite their critical applications from scratch, the update helps them further improve their existing applications of distributed computing models. Legacy update is heavily supported by multi-cloud and hybrid cloud deployments.

The IT industry’s adoption of containers, coordination, deployment, and management of application packages and workloads is another trend of modernization. A more separate approach to development and operations – specifically the architecture of microservices – is introduced through containers rather than a legacy implementation.

Advantages of updating the application

accelerated digital transformation

The need to transform business to build and rapidly introduce new capabilities motivates application modernization. Deploying a new system takes days instead of hours with DevOps and cloud-native tools, helping businesses transform faster.

Enhanced developer experience

Containerization and adoption of a cloud-native architecture allow you to rapidly develop new applications and services. Developers don’t have to worry about merging and publishing multiple changes in a short period.

express delivery

It is possible to reduce the time to market from weeks to hours by adopting best practices from DevOps. Application update allows code changes to be deployed quickly and without real human intervention. Hybrid cloud platforms are ideal for deploying enterprise applications because A multi-cloud environment that helps increase efficiency by automating processes. This is called “build once, publish to any cloud”.

Faster integration and build

Multiple code streams can be combined into one using DevOps principles. You don’t have to worry about changes in the current environment since recent deployment is possible with the entire integration cycle merging at once.

Why move the app to the cloud?

The desire to quickly add new capabilities leads to applications being updated. Adopting DevOps and cloud-native tools reduces the time and resources required from development to deployment, allowing businesses to transform faster. Most companies moving to the cloud want to be more flexible, save money, and reduce time to market.

Most organizations choose the simpler “leverage and transform” model because they realize that cloud-native solutions and architectures can provide greater value and innovation than traditional infrastructure-as-a-service options. Retaining legacy applications and architectures will hamper their ability to innovate, improve, and speed. Cloud-native is the future of application development, enabling rapid prototyping and dissemination of new ideas.

You need to reorganize people, processes, and workflows to be “cloud-native”; Create apps with the cloud in mind. This entails a cloud-native development strategy that aligns with the overall business development strategy.

Refactoring or rebuilding traditional applications on container platforms into cloud-native microservices is also effective for seamless migration to the cloud. Cloud-native microservices allow customers to benefit from end-to-end scalability and flexibility to ensure seamless orchestration.

Many cloud-native architectures address the requirements of rapid up-and-down scaling, thus improving computing and cost. Businesses these days require faster development, integration, and deployment, which require simultaneous development and deployment cycles that reduce their time from days to hours.

6 rupees for cloud migration

The value proposition and potential opportunities of each application are clearly defined by its scoring following the 6R system. In short, the “six rupees” to migrate to the cloud, let’s say they are a variety of approaches that can be used when migrating applications to the cloud. Each R stands for a distinct approach, value, and outcome.


Rehost comes at the top of the list because it is the strategy most used by companies looking to move their IT infrastructure to the public cloud. Rehosting, also known as “lift and shift”, is a straightforward way to move your on-premises IT infrastructure to the cloud, requiring minimal modification to workloads and methods. Simply copy your servers to your cloud provider’s infrastructure and move them there.

Although the cloud provider now manages the hardware and hypervisor infrastructure, you continue to manage the operating system and installed applications. With the help of well-known tools from cloud service providers like AWS Cloud Endure and Azure Site Recovery, you can move your servers to the cloud with great ease and speed.

Restore the statute

Backtracking allows you to use cloud migration to upgrade your operating systems or databases, for example, instead of upgrading and transforming servers. Migrating to the cloud may require creating a platform if you have older operating systems that your cloud provider no longer supports.

When moving to the cloud, you may want to switch from a commercially supported platform to an open source platform to further enhance your experience. However, the architecture of your applications will not change because you are only changing the core services while keeping the underlying application code the same.


Changing the application code to take advantage of cloud-native services is meant to rebuild, which can be considered an “application update”. While it is likely that you would prefer to use serverless cloud service provider functionality rather than server-based applications, choosing to rehost or restart an application first is a common strategy for companies looking to gain some momentum behind their cloud migration.

This is the most resource intensive option, however, there is a risk that if you rehost an app that you want to update or reorganize, the rebuild priorities will be reduced, and the app may never be updated.

buy back

Managing software installed on the infrastructure you are using may not be necessary if you are using commercial off-the-shelf (COTS) applications available as software as a service (SaaS). It’s also possible that you’d prefer to use a completely different app from a different vendor.


The decommissioning process involves identifying applications that are no longer required before migrating to the cloud. To avoid paying for application infrastructure that does not provide any commercial benefit, it is crucial to stop unnecessary applications and data.


Retention explains the situation where companies may have applications in their portfolio that migrating to the cloud is not an option because they are simply not good candidates. Moving it to the public cloud may not make financial sense for some applications because you have just invested in a new on-premises infrastructure or because the vendor refuses to support a specific software in a public cloud platform.

Nowadays, there are several reasons to keep the app local, but this depends on your situation and business needs.
