Challenges Faced with VMWare
Sierra-Cedar used VMware for reliable and scalable server virtualization in its private data centers. As its reliance on
VMware grew, the company faced several challenges, including:
License Cost Increases:
Sierra-Cedar anticipated significant licensing cost increases for its 1,800+ VMware instances at the next renewal, and expected no added value or cost recovery options.
Vendor Lock-in:
Sierra-Cedar’s heavy reliance on VMware for large-scale virtualization posed risks due to single-vendor dependence. This limited flexibility to adopt new technologies like AI and data analytics to meet future client needs.
Limited Support for Infrastructure as Code (IaC):
Sierra-Cedar invested heavily in developing its tools using IaC to create, manage, and maintain cloud infrastructure at scale. Compared to VMware, AWS APIs provided additional flexibility to scale and deploy resources using automation.
The Solution
After thoroughly evaluating cloud-native alternatives, Sierra-Cedar decided to migrate its hosting service clients from VMware hosts to native EC2 instances in AWS. This move aimed to elevate operational efficiency, enhance scalability, and control costs by adopting cloud-native services and reducing dependency on traditional data center software, including VMware.
Implementation Process
Sierra-Cedar meticulously planned and executed the migration of over 1,800 VMware instances to EC2 over 15 months, involving 30+ clients and 400 application instances.
