FAQ - Legacy application modernization services

How much does application modernization cost?

The cost of application modernization can be influenced by the size and complexity of the application, the specific goals of modernization (such as moving to the cloud, updating the user interface, or improving scalability), the technologies involved, and whether the work is done in-house or outsourced.

To narrow it down, take into account the following factors:

  1. Scope and complexity: Larger and more complex applications will require more effort to modernize. This includes understanding the existing codebase, dependencies, and functionality that needs to be replicated or improved.
  2. Modernization strategy: The approach taken to modernize the application can significantly impact costs. For example, re-hosting (lifting and shifting to the cloud) might be less expensive in the short term compared to re-platforming (modifying the app to better suit cloud environments) or refactoring (rewriting parts of the application to take full advantage of cloud-native technologies).
  3. Technology stack: Updating or changing the technology stack (e.g., moving from a monolithic architecture to microservices) can add to the cost. Newer technologies might require additional training for your team or the hiring of new talent.
  4. Infrastructure and tools: Moving to cloud services or adopting new development and deployment tools can introduce additional costs. However, these can be offset by savings in areas such as reduced server maintenance costs.
  5. Security and compliance: Ensuring that the modernized application meets current security standards and regulatory requirements can add to the project's cost.
  6. Testing and Quality Assurance: Thorough testing is essential to ensure that the modernized application performs well and is free from bugs. This includes functional testing, performance testing, and security testing.
  7. Training and change management: Training staff to use new technologies or processes and managing the change within the organization can also contribute to the overall cost.

In general, the cost of application modernization can range from a few thousand dollars for small, simple applications to several hundred thousand or even millions of dollars for large, complex systems. It's important to conduct a thorough assessment of the existing application and your goals for modernization to develop a realistic budget.

How long will it take to modernize a legacy systems?

The duration of a legacy system modernization project depends on several factors, similar to those affecting cost. These factors include the size and complexity of the system, the chosen modernization strategy, the technology stack, and the available resources. Here's a rough guideline on what to expect:

  1. Small projects: For smaller systems or projects where the scope is limited to updating certain components, the modernization process can take from a few weeks to a few months.
  2. Medium projects: For medium-sized projects, especially those involving moving to the cloud, re-platforming, or partial rewriting, the timeline can range from several months to a year.
  3. Large and complex projects: Large-scale modernization efforts, such as fully rewriting a legacy system, adopting microservices architecture, or extensive cloud integration, can take from one to several years.

The modernization process typically involves several stages, each affecting the timeline:

  • Assessment and planning: Understanding the current state of the legacy system, defining the modernization goals, and planning the process. This stage can take weeks to months, depending on the system's complexity.
  • Proof of Concept: Developing a proof of concept to validate the chosen modernization approach. This stage is variable but can take from a few weeks to a few months.
  • Implementation: The actual work of modernizing the system, which can vary widely in duration based on the project's scope and complexity.
  • Testing and Quality Assurance: Ensuring the modernized system meets all functional and performance requirements. This stage overlaps with implementation and can extend beyond the initial rollout.
  • Training and deployment: Training users and deploying the modernized system. The duration of this stage depends on the system's size and the number of users.

Key considerations affecting the timeline of modernizing legacy applications:

  • Availability of resources: Having enough skilled personnel available to work on the project can significantly impact the timeline.
  • Vendor or third-party dependencies: Delays can occur if the modernization involves waiting for external vendors or third-party components.
  • Unforeseen challenges: Legacy systems often contain undocumented features or complexities that become apparent only during modernization, potentially extending the timeline.
  • Change management: The need to manage organizational change effectively, including training for new processes or technologies, can also influence the duration.

What are the types of application modernization services?

Legacy application modernization services encompass a range of strategies and solutions designed to update and enhance legacy systems, making them more efficient, scalable, and aligned with current business needs and technology standards. These services can be broadly categorized as follows:

Rehosting:

Also known as "lift and shift," this involves moving applications from on-premises infrastructure to the cloud without changing the application's code. Rehosting is often the first step in modernization, offering immediate benefits such as reduced infrastructure costs and improved scalability without the need for significant redevelopment.

Replatforming:

This involves making minor modifications to the application to take advantage of new cloud infrastructure capabilities without fundamentally changing the core architecture of the legacy application. Examples include using cloud-managed databases or adopting cloud storage solutions.

Refactoring / Rearchitecting:

This approach involves making significant changes to the legacy application's code to fully utilize cloud-native features and capabilities. It often involves moving to a microservices architecture, which allows for better scalability, maintainability, and deployment flexibility. This process can be more time-consuming and costly but results in a more future-proof and scalable application.

Rebuilding:

Rebuilding a legacy application involves rewriting it from scratch while preserving its scope and specifications. This option allows for adopting modern programming languages, frameworks, and architectures, offering an opportunity to address legacy issues and improve performance and scalability.

Replacing:

This involves replacing the legacy system with a new application or a set of applications that fulfill the same business needs. The new solution can be custom-built or purchased as an off-the-shelf product. Replacement is considered when the existing system is too outdated or costly to maintain and modernize.

Encapsulation:

Encapsulation involves leveraging the existing functionality of legacy applications by encapsulating data and functions and making them available as services via an API. This approach allows for incremental modernization and enables legacy systems to interact with modern applications.

Software Portfolio Management:

This service involves analyzing and managing the entire software portfolio to identify modernization opportunities, ensure software compliance, manage licenses, and optimize software investments. It's crucial for strategic planning and resource allocation in large-scale modernization projects.

Cloud Integration Services:

These services focus on integrating cloud services with existing applications to enhance functionality, scalability, and performance. It includes integrating with cloud-based storage, databases, AI/ML services, and serverless computing platforms.

DevOps and Continuous Integration/Continuous Deployment (CI/CD) Implementation:

Modernizing an application often includes adopting DevOps practices and implementing CI/CD pipelines to streamline development, testing, and deployment processes. This enhances agility, improves product quality, and accelerates time to market.

Security Modernization:

Updating security protocols, implementing modern encryption methods, and integrating security services to protect against current threats. This is critical as older applications often lack the defenses to deal with today's sophisticated cyber attacks.
