Technology has been taking swift strides this decade, and digital transformation is imperative for every business. While shedding outdated processes and legacy technology, business leaders are ready to invest heavily in new technology and digitization to witness the astounding outcomes of this digital transformation. For enterprise transformation with the help of digital transformation, solution transformation, and data transformation, innovation is becoming a top priority for businesses. Every organization is predicted to be a software organization at some level.

Nowadays, businesses realize they can provide breakthrough digital customer experiences using cloud-first solutions and its services. Vendors of major enterprise systems – like Microsoft, SAP, and Oracle – have switched their attention to their cloud products, ceased supporting their existing systems and stimulated their clients to switch to the cloud first by providing attractive benefits like slashed prices, security enhancements, development and low maintainability with new features and services. Many businesses shifted to leverage their capabilities, ...
... while others forcefully made the shift during the pandemic.

Monoliths are large code bases which contain all the logic needed to run an application anywhere. It is self-contained, employable and includes a lot of functionality. It is composed of many modules that represent different functionality in an application. Everything within the monolithic architecture is connected or can be connected to anything else. All the relevant code in this project is kept in a single repository.

Cloud-based enterprise systems enable businesses that regularly require large amounts of computing power to provide some digital product or digital experience. They add capabilities that include advances in data analytics technologies, quick adoption of agile product development approaches and automation.

In the microservice architecture, the code is broken into pieces and converted into services. Each microservice is designed and implemented to do a more specific task. Specific services are independently built, deployed, operated, and scaled. They can take requests and potentially call each other to fulfil these requests.

Migrating from monolith to microservices – application modernization

Step 1: Gain a comprehensive understanding of the existing monolithic application
Step 2: Use the domain-driven design to expand the identified services and fragment the frontend and backend
Step 3: Build services and eliminate the monolithic architecture incrementally
Step 4: Evolution of your enterprise application with microservices

Services in a microservice architecture are planned around business concerns and not technical concerns. So, there may be a need to create larger services instead of smaller services and defining service boundaries may be an iterative process.
