Cloud Application Modernization Services are Critical for Business Success
Published: 2022-06-17 08:18:59

Application modernization has become a necessity today, especially for businesses lacking in capturing the market because of technological immaturity. Companies that are still relying on on-site solutions and legacy systems must update, upgrade, change, reformat, and re-platform their digital solutions.

Doing so will empower them to work at par with the existing market trends, experience operational flexibility, reduce costs, and streamline operations while making them more productive than before. 

The process of repurposing the legacy systems is called application modernization. [Cloud application modernization](https://www.devitpl.com/cloud-services/cloud-application-modernization/) is one part of this process.
 
##Explaining Application Modernization and Optimization

The current and upcoming market structure necessitates that businesses become fluid enough to adapt, react, and perform according to the market. Plus, they need to execute the required changes with speed and efficiency or lose market share for being obsolete. 

This poses a challenge for the Infrastructure and Operations leaders, CTOs, CIOs, and technical leaders. They must build a system that enables companies to support rapid and pertinent innovation plus growth. 

###Application Modernization and Optimization

Companies repurpose and reprogram their existing infrastructure and software to become modern. Sometimes the CTOs decide to consolidate the legacy systems or rewrite their code to function like a modern application. 

This is done while considering the company needs and the market trends. In the end, cloud app modernization services provider a plethora of benefits. 

####Monolithic to Granular Structure: 
Legacy software and solutions have a monolithic architecture. They are built on a single-tier, which also includes a database and interface into a single program.

Modernizing them means giving these solutions a granular structure where every segment works independently of others, but when combined, they all work together to run a single application. This type of architecture makes it easier to maintain, update, and alter the solutions. 

####Cost-Efficient
Compared to a monolithic application structure, the granular or microservices format is also cost-efficient. This is because to update a feature in the legacy software means changing or editing the entire codebase so that every aspect conforms to the updated version. With application modernization, the architecture changes to take a new form, which is cost-efficient.

####Enhances Performance
When you compare a legacy application with one built with contemporary technologies, there will be starking differences. The latter will perform better in terms of performance, and speed, have a better interface and provide an impressive customer experience.

The commiserate result of all these aspects is that the user experience will be better, leading to lead conversion and revenue generation. 

##Application Modernization Patterns

We can modernize a solution with three patterns;

####Rehosting:
Rehosting is the simplest form of modernization where we simply pick up the application code and move it to another form of infrastructure. Mostly, this is moved to the cloud services like AWS, Azure, etc. In most cases, there is no alteration done to the code.

However, in cases where changes are required or done to the application code, then we can call it Replat forming. With cloud application migration, the application’s security is considered to be the primary concern. Hence, it is critical to pick the best cloud service provider with higher security and efficiency. 

####Refactoring
In refactoring, the entire code base is restructured or rewritten to suit the modern-day application development architecture. The developers work on the code to make it compatible with the cloud architecture. They can split the monolithic application structure 
into a microservices one.

##Key Technologies Used for Cloud Application Modernization Services

Organizations working on the modernization and optimization of an application use different types of technologies and tools. These are;

####Cloud Computing
At its very core, cloud application modernization leverages private, hybrid, and multi-cloud solutions to modernize strategically. In this, while security is the critical factor considered for the migration part, the developers also look at latency and the overall architecture.

####Containerization
With technologies like Kubernetes and Docker, developers deploy parts or complete applications in a separate environment. This dedicated environment is self-sufficient to host some features or full-fledged applications. With containerization, the greatest benefit we can leverage is scalability.

Plus, a well-executed application optimization and modernization process will ensure scalability, resilience, application security, compliance, and adaptability.
