Overview: Application Modernization<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

With the recent Covid-19 disruption, digital transformation of enterprises has increased multifold. The need for an agile and scalable IT environment to meet the demands of the ever-growing customer needs is also on the rise. The digital transformation, though needed now more than ever, is not any easier in these times, with monolithic architectures holding back companies from a quick and smooth transition.<\/p>

Digital transformation means little if it misses out the key components of cloud migration and application modernization. The time has come for all enterprises to quicken the process of application modernization to remain ahead in the market race.<\/p>

To put it in simpler terms, Application Modernization is all about dividing the legacy applications into their own individual functions. This way, each function will be capable of running on its own with the help of containers, making the framework independent, scalable, faster-to-deploy, and agile.<\/p><\/div><\/div><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Application Modernization is more than just moving offline business process to digital platforms. Micro services for each function must be developed based on legacy applications, so that productivity is enhanced and cost savings achieved.<\/p>

A complete application modernization means moving the underlying architecture from monoliths to micro-services, migrating from physical servers to cloud computing, and moving the delivery methods from waterfall to DevOps. While some organizations undergo application modernization in a gradual process due to financial constraints, others opt for a complete overhaul. Whatever the approach, one thing to keep in mind is to align these three critical aspects of the IT infrastructure.<\/p><\/div>

It is important for organizations to readjust their legacy applications with the new business requirements. Enterprises must turn into full-fledged digital-native enterprises and create new business value from aging legacy applications, without having to reinvest. There are definitely mission-critical applications which must run 24\/7 in a year, and keeping them for a complete overhaul is not the right thing to do. Instead, what enterprises can do is to implement application modernization for each application or function without disturbing the existing application stack<\/p><\/div><\/div><\/div><\/div><\/section><\/div><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

CloudEngin Application Modernization helps enterprises in maintaining, extending, deploying and managing their applications, so that they meet the current and future business needs. This depends on the company\u2019s situation, which will be driven by factors such as strategic business initiatives, application architecture, time, cost, and available skills.<\/p>

A legacy app that has some functionality, which is still useful, can sometimes be replaced with a more flexible cloud-based solution. The consumption of these services changes from a purchased license to a pay-as-you-go subscription.<\/p><\/div><\/div><\/div>

It\u2019s about moving to new application architecture where you can utilize all the modern programming as well as micro-services: a win-win situation.

In encapsulation, the monolithic application is broken, encapsulating data and functions in the application and rebuilding those individual components into micro services application through a new application programming interface. This will help your enterprise to leverage and extend the application\u2019s features and value to change with the evolving needs of the business.<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>

As enterprises move towards a complete digital transformation, one common challenge they face is the monolithic architecture of their legacy applications. With legacy applications based on single code and single-tiered application, enterprises tend to face more challenges as they are vulnerable to risks. Here are some challenges:<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Security<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

The legacy applications do not have the necessary security controls because of the traditional architecture, unsupported versions, old tools which expose the enterprises to threats, and other vulnerabilities and security risks.<\/p><\/div><\/div><\/div>

Higher Dependency\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t

In the legacy applications setting, the teams are highly dependent on each other as they work in traditional silos to develop and deploy applications. This can sometimes lead to high cohesiveness and lack of collaboration, which increases the cost and time-to-market of applications.<\/p><\/div><\/div><\/div>
