Smart companies and public sector organizations are always looking for new ways to expand their technology stack, increase operational efficiency and reduce costs. However, many still rely on decades-old mainframes and legacy systems.
But such legacy systems don’t fit into the modern technology stack and lack the scalability, agility and cost efficiency needed to reliably support and drive business functionality. Moving these inefficient mission-critical environments to a cloud platform like AWS is a strategic decision that offers many technical and cost-saving advantages. But, as with any major technical initiative, there are challenges businesses must address proactively to ensure a seamless transition to the world’s largest cloud platform.
Moving aging mission-critical environments to the AWS Cloud provides multiple ongoing advantages, including:
Increased Agility and Scalability: With Amazon EC2, users can dynamically and even automatically deploy virtual instances to meet their scalability demands. By enabling enterprises to scale up and down as needed, Amazon EC2 on-demand resources ensure mission-critical applications and databases support fluctuations in business activity while eliminating inefficiencies.
Cost Savings: Cloud migration can offer tremendous cost savings by eliminating the need for enterprises to spend time and money in modernizing and supporting end-of-life systems. AWS’s pay-as-you-go pricing model also enables efficient utilization of systems and reduces waste.
High Availability and Disaster Recovery (HADR): Two non-negotiable features of a secure, stable IT system are continuous availability and the ability to remain online during unforeseen events. The built-in HADR functionalities available on the AWS Cloud make it possible for an organization to be certain that even during disasters their data and business continuity are fully secured.
Ease of Internal and Regulatory Compliance: AWS Cloud offers a variety of compliance and security features and services, including CloudTrail and Identity and Access Management (IAM) to assist enterprises in meeting multinational regulatory requirements and safeguarding confidential business data.
Many organizations’ IT infrastructures rely heavily or exclusively on legacy systems, which serve as the foundation for all daily business functions. Migrating those systems to the cloud is a monumental task that requires meticulous preparation and execution by expert teams to ensure accuracy and a seamless transition.
An experienced partner like mLogica, with the right mainframe and legacy systems migration solutions, can proactively address any challenges to ensure fast, seamless modernization. Such challenges can include:
Incomplete Assessment of Legacy Systems (The Last Mile Challenge):
COBOL, CICS, VSAM and Db2 databases are frequently the largest, most top-of-mind components of legacy systems. However, addressing only these technologies and failing to comprehensively assess and analyze their critical dependencies on exotic languages such as Assembler, Easytrieve, Telon and PL/1 can stop your project in its tracks. Even databases such as IMS and IDMS are often missed during assessments, however it’s critical that they also be analyzed and expertly addressed for the migration to be successful.
This lack of attention to critical underlying systems inevitably leads to one of the most common causes of modernization failure we see: The Last Mile Challenge. This occurs when major components of legacy systems are modernized correctly, but are ultimately unable to function in the new platform because critical supporting technologies have been ignored or migrated incorrectly.
Data Migration Accuracy Without Automated Technology:
There are two main methods of modernizing data to the cloud: manual conversion of millions of lines of code, which takes years and is highly prone to human error, and automated migration, which is faster, highly efficient and eliminates the need for large conversion teams.
Traditional manual migration also prevents users from accessing business data for lengthy periods, leaving leadership unable to leverage key information required to support strategic decision-making. By contrast, using automated solutions to move mission-critical mainframe and legacy systems to the cloud is much faster—ensuring data security in flight, minimal downtime and a seamless transition.
Data Security: An organization’s sensitive data is processed by mission-critical systems, and businesses are required to comply with strict security standards and procedures to ensure regulatory compliance. A comprehensive data security plan and governance policy are essential to protect business-critical information and meet regulatory standards.
Minimizing Downtime: Any interruption to vital applications and databases may have drastic implications on business continuity. Therefore, it is essential to collaborate with a veteran cloud migration services provider that can ensure minimal disruption during and after cloud migration.
Moving mission-critical environments to the AWS Cloud can be a paradigm-shifting decision for any organization, offering critical functionality advances including on-demand scalability, cost savings, increased agility and top-level security.
However, the success of any cloud migration depends on expert planning and execution. By hiring a veteran migration services provider like mLogica, you get to quickly and cost-effectively enjoy the benefits of the AWS Cloud while remaining focused on your business and ensuring seamless service availability for your team and your customers.
