AS400 Migration to the Cloud

Benefits of AS400 to cloud migration

Migrating legacy systems to the cloud can play a crucial role in future-proofing your organization. Here are the results you can expect from a well-planned and well-executed cloud migration strategy:

  • Accessibility: As long as you have an internet connection, you can access your business’ data via desktop or mobile devices.
  • Security: Cloud services often come with built-in, customizable application security measures, so you can sleep easier at night knowing that your company’s and its customers’ sensitive information is protected.
  • Cost-saving: Cloud environments are cheaper to maintain than physical servers. Plus, under a “pay-as-you-go” model, you can only pay for the amount of cloud computing you need each month.
  • Scalability: With a more agile system, you can accommodate spikes in demand, as well as adopt powerful new technologies — such as artificial intelligence (AI) and machine learning (ML) — to streamline workflows.

Challenges with AS400 migration to the cloud

Despite the many advantages of legacy modernization, migrating AS400 applications to the cloud can be a long and complicated process — which is why many companies resist the change. Here are the main challenges businesses face:

  • Security concerns: Businesses that manage highly sensitive information — such as those in the healthcare sector — can’t risk a data leak during their cloud migration. And in most cases, stakeholders lack the tools and expertise necessary to plan and execute a totally secure migration.
  • Change management: Cloud migration enables new workflows through automation, which can disrupt a business’ internal processes and culture. Some organizations are simply not prepared to undergo these changes.
  • Database restructuring: The AS400 database is outdated, making it difficult to integrate with other system applications. This means the database must be restructured for a cloud environment, which requires significant time, effort, and technical knowledge.

Cloud providers

Which cloud environment is best for your business’ unique systems and workflows? Here’s a quick look at the top providers to choose from when migrating AS400 applications to the cloud:

  • AWS: Users of Amazon Web Services (AWS) have access to Infinite I, a toolkit that allows developers to efficiently recompile and deploy AS400 applications in the cloud.
  • Google: By migrating legacy AS400 applications to Google Cloud, organizations gain access to a wide range of other cutting-edge cloud resources, as well as Google’s 24/7 support plan.
  • Azure: Like AWS, Microsoft Azure offers a smooth migration and deployment of AS400 applications through the use of Infinite I.

Migrating AS400 applications to the cloud can be a long and complicated process, which is why so many companies avoid modernization and continue running mission-critical tasks on outdated software. However, by relying on legacy systems, businesses lose their competitive edge, as well as miss out on opportunities to cut costs, enhance data security, and improve scalability.
