Modern Techniques and Tools for Legacy Software and Data Modernization
Leonid Nerayev, DevOps Division Manager, CloudHome Group
As businesses continue to rely on technology to run their operations, keeping software and databases up to date becomes increasingly important. Legacy software and databases can be difficult to maintain, and their complexity can make it difficult to update or modify them to meet new business needs. This is where modern techniques and tools for legacy software and data modernization come into play.
The market for legacy software and data modernization is expected to expand significantly in the coming years. According to Gartner, the global application modernization services market will grow from $8.8 billion in 2019 to $16.4 billion in 2024. In response to rising demand.
Software modernization involves the use of modern software development techniques and tools to update legacy software to meet current business needs. A detailed gap analysis is the best way to begin the modernization process. This analysis identifies the differences between the current software and the desired end state and outlines the steps required to get there.
Modern software development techniques rely on:
Microservices – A software architectural style that structures an application as a collection of loosely coupled services. This approach makes it easier to develop, test, deploy, and scale individual services independently, making the development process more efficient and effective.
Containers – A lightweight and portable way to package and deploy software applications. This allows the software to be deployed consistently across different environments, making it easier to maintain and manage.
Open-source software – A type of software whose source code is freely available to the public, allowing anyone to use, modify, and distribute it. Open-source software is often free and is constantly updated by a large community of developers, making it a cost-effective and reliable option for modernization.
Low-code development is another modern software development technique that has been recommended. Low-code development enables non-technical staff to create software applications using visual tools and pre-built components. This approach makes it easier to include non-technical staff in the development process, increasing the development team’s efficiency.
Another critical aspect of modern software development is platform engineering. Platform engineering entails designing, developing, and managing the underlying infrastructure that supports a software application. This includes the use of cloud computing and other technologies to ensure that the software application is efficient, scalable, and reliable.
Development methodologies such as DevOps and SRE should be implemented to ensure efficient and effective software development. DevOps is a set of practices that combines software development and IT operations to improve the speed and quality of software delivery. SRE, or Site Reliability Engineering, is a set of practices that ensure the dependability, scalability, and efficiency of software applications.
Another critical component of legacy software modernization is data modernization.
OLTP and OLAP modernization are two critical aspects of data modernization.
OLTP, or Online Transaction Processing, is a type of database system used to process transactions such as purchases or reservations. OLAP, or Online Analytical Processing, is a technique for processing large amounts of data for analytical purposes.
Another important aspect of data modernization is the use of data pipelines and data lakes. Data Pipelines are a set of processes that move data from one location to another within an organization, typically from source systems to target systems. A data lake is a large, centralized repository that houses all of an organization’s structured and unstructured data. Data lakes are intended to make it easier for businesses to store and analyze large amounts of data, making it easier to identify trends and insights that can help drive business decisions.
Democratization of Software Development
One of the key focuses is the democratization of software development. This approach involves making software development available to a broader range of people within an organization. Organizations can improve the efficiency and effectiveness of the development team by involving non-technical staff in the development process, allowing them to develop software faster and more efficiently.
Organizations should use modern software development tools and techniques that are designed to be accessible to a wide range of people to achieve this. Low-code development tools, for example, enable non-technical staff to create software applications using visual tools and pre-built components. In this way, we are democratizing software development.
Modern Software Development Lifecycle
Planning, design, development, testing, deployment, and maintenance are all stages of the modern software development lifecycle.
As previously stated, the planning stage involves conducting a detailed gap analysis to identify the differences between the current software and the desired end state. This analysis is used to create a modernization plan that outlines the steps required to get there. The architecture and infrastructure of the software application are designed during the design stage. Choosing the appropriate technology stack, designing the software architecture, and developing the underlying infrastructure are all part of this process.
The development stage involves writing the code for the software application. To improve efficiency and effectiveness, modern software development techniques such as microservices, containers, and low-code development are used.
The testing stage involves testing the software application to ensure that it is functioning as intended. This includes unit testing, integration testing, and acceptance testing.
The deployment stage involves deploying the software application into production. Modern software development tools like DevOps and SRE are used here to ensure that the deployment is efficient, reliable, and scalable.
The maintenance stage involves ongoing maintenance of the software application, such as bug fixes, security updates, and performance enhancements. This is where modern software development tools and techniques, such as cloud computing and data lakes, are used to ensure that the software application is efficient, reliable, and effective.
Modern DevOps tools and vendors
Modern DevOps tools and vendors play a critical role in the software development lifecycle.
To become a Cloud-Native organization and maximize business value with modern applications, organizations should consider using a variety of modern DevOps tools and vendors, as well as open sources, such as:
