Database Modernization: - COTS to Opensource

Database Modernization: - COTS to Opensource
June 13, 2019

Today, applications are shifting away from legacy monolithic architecture to a service-oriented architecture by leveraging container, cloud, and related technologies. Moreover, a key role is being played by open source based databases in such initiatives.

Enterprises that successfully address the challenges of a data-modernization project are poised to take advantage of many benefits, the primary one being the ability to bring in more stable, scalable, and flexible databases and moving to more robust RDBMS and NoSQL platforms.

According to recent research, by 2020, open source software in IT portfolios will increase at 30% CAGR. By 2022, more than 60% of all the global organizations will improve their internal skills related to open source to better open source use in production, which represents an increase of 20% from today.

By 2022, more than 60% of all the global organizations will improve their internal skills related to open source.

The most important aspect of modernizing application assets is modernizing the database and eliminating monolithic code so that discrete functions of core applications can be leveraged for a variety of benefits. Old application architectural constructs and monolithic code cause unmanageable maintenance burden, which delays change and enhancement requests, which in turn, frustrates users and business managers. To create agility, applications that were designed with old standards must be fundamentally re-constructed to unlock their massive value, retain the competitive advantage facilitated by those applications, and recover the business rules in reusable components. This benefit brings some challenges for database modernization. Data and application play a decisive role while looking for database modernization—be it moving to the cloud or legacy to new database technologies.

HCL Point of View on Database Modernization

Considering data and application complexity along with cost-benefit analysis and cost of migration, compatibility, and integration, product roadmap, market, and organization readiness cloud do give a good option for database modernization. At the same time, the open source database gives more cost benefits while moving away from legacy commercial off-the-shelf to open source and their availability on cloud models, i.e. public, private, or hybrid giving an added advantage of the cloud and open source database.

With many databases available in the market, such as MongoDB, Cassandra, PostgreSQL, and MariaDB, PostgreSQL seems to be a close competitor for database, such as Oracle that holds a bigger market share.

PostgreSQL, a database platform for digital business, delivers the premier opensource-based data platform for new applications, cloud re-platforming, application modernization, and legacy migration. PostgreSQL integrates with enterprise technologies and infrastructures for hybrid-cloud management, data integration, and data warehousing. Customers can benefit from PostgreSQL, which is the highest performing, most reliable, flexible, open, and cost-effective data management platform available.

Enterprise DB Postgres delivers a bridge between development, operations, and database administrators for data that enables rapid application development with the required visibility and control. The bridge is a prerequisite for using DevOps processes in IT or in the line of business to timely deliver high-quality digital business applications. EDB Postgres Ark lower risk and costs of using public, private, and hybrid clouds. DBaaS infrastructure simplifies the building, deployment, and maintenance applications on multiple cloud infrastructures including Amazon EC2, Open Stack, and Microsoft Azure.
