For many enterprises, the cloud migration journey is becoming more complex, operationally speaking. As organizations move more applications, workloads and infrastructure to the cloud, they’re likely to be using services from multiple public cloud providers; 55% of organizations in IDG’s 2020 Cloud Computing Study currently use multiple public clouds.
Multi-cloud environments provide a multitude of benefits, including access to best-of-breed platforms and services and greater flexibility. But there are obstacles to this approach, in the form of increased complexity and the potential for increased costs.
As multi-cloud environments grow, IT teams will need to address these challenges to ensure their investments are meeting broader business objectives. We asked our community of B2B technology influencers for their thoughts on the best way to manage and optimize workloads across different public cloud providers in a multi-cloud environment. We grouped their responses into three main takeaways.
IT leaders who have embarked on a cloud modernization journey understand the importance of prioritizing which applications and workloads to move from on-premises environments to the cloud. It’s equally important to make sure you’re choosing the right cloud service provider (CSP) for each of the applications or workloads you’re migrating.
“As part of a cloud migration strategy, establish a cloud decision framework to provide a methodical approach, based on workload characteristics and cloud platform capabilities, to guide workload placement in a multi-cloud environment,” said Sook Chua, Ernst & Young LLP Principal, Technology Consulting.
Jack Gold (@jckgld), President and Principal Analyst at J. Gold Associates, LLC, said the multi-cloud consideration set should include which services are available on each cloud instance (e.g., frameworks, app stacks from the various cloud providers, third-party availability as a service) and specialized hardware acceleration needs for specific workloads (e.g., artificial intelligence, machine learning, natural language processing, image processing).
Because different use cases can vary by cloud provider, it’s wise to take the extra time and steps to map workloads to the different CSPs, said Will Kelly (@willkelly), technical marketing manager for a container security startup. For example, Kelly said, for cloud storage, look for a CSP that offers the best pricing, while analytics workloads may be best served by a CSP with the best artificial intelligence stack.
Steve Prentice (@StevenPrentice), a technology integration specialist, offers some additional criteria for assigning applications to cloud platforms, including security, cost, practicality, mission critical and urgency, uniqueness and location. As IT teams work through these priorities, they may find that some workloads and applications, and the data they contain, may be better off spread across multiple CSPs. “Distribute your data across multiple providers to reduce risk and maximize redundancy, security, and resiliency,” he said.
Because cloud services can be deployed easily across different parts of the business, it’s important for IT teams to take a holistic approach to managing a multi-cloud environment to keep costs in check.
