Cloud modernization refers to migrating an organization’s legacy applications, infrastructure, and data center systems to cloud-native solutions due to the adoption of cloud-based services.

As businesses adopt cloud-based services at a growing phase, the imperative to migrate legacy applications, infrastructure, and data center systems takes center stage. Within this blog, we delve into the complexities of Cloud Modernization, illuminating its necessities, delving into its diverse applications, and demystifying the intricacies of the migration process.

What is Cloud Modernization?

Cloud modernization aims to improve agility, scalability, security, and cost-efficiency while ensuring the organization’s IT assets align with current business needs and technological trends.

This strategy intends to assist IT and business executives, program and project managers, product owners, operations and infrastructure managers, and other stakeholders who want to modernize their applications using the cloud infrastructure. It includes explanations of how to identify mission-critical applications, evaluate different approaches to modernization (such as refactoring, rearchitecting, or rewriting), and explain why those applications would benefit from improved scalability, performance, security, and reliability when they are modernized.

Three approaches can be considered for cloud adoption.

  • Re-hosting: Migration with no or minimal change. It mainly includes moving services, data, and resources from an on-premise environment to a cloud platform without significant changes in architecture or workflow.
  • Re-platforming: It mainly includes modernizing components of infrastructure for higher-level optimization. In this process, multiple components are upgraded before infrastructure migration.
  • Refactoring: It means performing high-level changes in infrastructure to achieve high results. It includes many significant changes in the architecture and code on which the application is working.

Why Is Cloud Modernization Needed?

Modernizing the cloud can benefit a business in many ways. The most obvious are cost savings, scalability, agility, security, and flexibility. With the migration to the cloud, businesses can optimize their operations and stay competitive in their particular markets by utilizing their cloud-native architectures, services, and technologies. A successful cloud modernization strategy helps meet business goals and deliver maximum value with desired outcomes at the corporate and individual levels.

What Are the Benefits of the Cloud Modernization Strategy?

  • Agility: Getting new products and services to market more quickly through cloud solutions is possible. The cloud offers a wide range of pre-built tools and services that businesses can rapidly develop and deploy new applications across a variety of devices.
  • Security: Cloud providers protect data and applications more quickly because they invest heavily in security. Cloud providers, including identity and access management, encryption, and network security, offer a wide range of security services. In some cloud providers like AWS (Amazon Web Services), there is support for Multi-factor authentication, which acts as an extra level of security over the password.
  • Flexibility: Cloud computing allows businesses to adopt remote working and flexible working arrangements, making it easier for them to integrate technology into their operations. It can generate a lot of positive effects on attracting and retaining top talent and helping employees maintain a healthy work-life balance.

What Are the Methods for Migration From On-Premise to Cloud?

  • Defining the Objective: Before beginning, one must determine what you want to achieve with cloud modernization. It includes assessing the current infrastructure and defining the goals to be achieved with the modernization of the infrastructure.
  • Current Environment Analysis: Thoroughly examine the working infrastructure and applications to determine which ones may be migrated, which can be retired, and which can remain as they are currently in their environment.
  • Choose the Right Cloud Platform: Decide which cloud platform and provider suits the business by evaluating different cloud platforms and providers. This step also includes identifying the cloud service that can suit the cost as well as the payload required for the current infrastructure.
  • Prioritize Application: Consider each application’s criticality, complexity, and benefits before prioritizing it for migration. To gain confidence and experience, one must start by working on less critical applications initially and then moving to the ones that are significant applications that require extra observation.
  • Setting up Cloud Native Architecture: Develop a sustainable, scalable, and resilient cloud-native architecture. It includes Implementing a cloud architecture that meets business requirements using modern tools and technologies.
  • Migration Plan: Migration requires careful planning, including timelines, resource allocation, and risk management. Make sure to develop a migration plan that minimizes the downtime and disruptions that might occur.
  • Test and Validate: To ensure that your cloud environment meets your performance and security requirements, you should test it thoroughly before and after migration to ensure it meets the requirements.

What Are the Best Practices for Cloud Modernization?

Cloud modernization involves migrating legacy applications and infrastructure to the cloud and optimizing existing cloud deployments to take advantage of the latest features and technologies.

It is essential to understand that upon applying these processes with thoughtfulness and discipline, organizations can determine which applications are suitable to be replaced, retired, or rehosted – versus those suitable for refactoring and rewriting to function natively on the cloud.

  • Conducting Thorough Assessment: Before starting, modernizing your infrastructure, applications, and processes requires a thorough assessment. This might help in identifying challenges, risks, and opportunities, which will help in performing better migration
  • Use Automation Tools: Reduce the risk of human error by automating the migration process. Monitoring performance, configuring applications, and provisioning resources can all be accomplished with these tools.
  • Implement Best Security Practices: To protect your cloud-based applications and data, you should implement best practices. Security measures can include encrypting data, using secure authentication mechanisms, and monitoring the network for security threats to protect the information.
  • Optimize and Improve: The cloud environment must be continually monitored and optimized to ensure it performs well, saving money and providing high levels of security. If any changes are to be made, they must be identified and implemented sequentially. This includes regularly reviewing your infrastructure and applications to identify areas for improvement and implementing changes as needed.

Conclusion

It takes careful planning, identifying the right resources, and adopting best practices to modernize application infrastructure properly. One can optimize our business processes and reduce costs using Cloud modernization services.

Modernization has many benefits, financial as well as technical. There has been a 40-50 percent cost reduction reported by most companies that are using cloud modernization for managing their infrastructure. Deployment cycles have been reduced from 90-120 days to almost a week because cloud modernization uses automation tools to increase productivity.

It has been possible to increase application response time by up to 10 times with the application of cloud modernization. It has been identified that code deployment for infrastructure provisioning has increased 100 times because of cloud-based techniques.
