5 Reason for Moving to Multi-Cloud



What is Multi Cloud ?

Multi-Cloud is not a platform, it's an approach, and it's about choice. An organization building its IT environment across multiple cloud platforms which enables them to deploy workloads on any number of different combinations of on-premises and public cloud providers. With Multi-Cloud comes the promise of agility and freedom.

The Multi-Cloud approach offers a range of options for efficiently leveraging the benefits of different platforms and empowers developers to pick and choose the best components for their use cases.

The Multi-Cloud approach started out of necessity and embracing and Multi-Cloud adoption is growing dramatically. Based on the 2019 Cloud Survey report from Flexera, 84% of enterprises are already working towards a Multi-Cloud strategy.

The Multi-Cloud approach is often a response/reaction to the value propositions for various cloud services, which focus on several key areas. What are those key reasons/drivers for moving to Multi-Cloud?

We have identified 5 main reasons for moving to Multi-Cloud.

  1. Cost effectiveness

One of the main requirements for moving to the cloud is cost effectiveness. With the right approach to workload and cost strategy, an organization can save a lot compared to its on-premise counterpart.

But how is the Multi-Cloud approach more effective? Isn't the migration bubble larger? Will sticking into one vendor save more?

Price competition of cloud vendors.

The Cloud Service Providers (CSPs) have a different, often similar set of services at different ranges of pricing. Organizations can enjoy the freedom of choice that allows them to maximize their ROI by choosing the most cost-efficient solution.
Even though the initial cost for Multi-Cloud setup may cost you more, it will save a lot in the long run. Placing the right workload into the right cloud vendor will save a lot of time, effort and money.

  2. Optimal Operational Environment.

Ability to pick and choose different CSPs services and private cloud solutions is not only beneficial on ROI, but also allows an organization to have the best available tools/services in their multi-cloud arsenal.

Key factors that dictate building the optimal operational environment
  • Performance
  • Security
  • Reachability
  • Regulatory compliance

For certain workloads, a serverless approach is better and for some workloads portability with containerization gives a better cost/performance. Mix and match of CSPs based on workload requirements can be an added advantage of Multi-Cloud adoption.

One cloud solution may be better suited for a specific task. For instance, utilizing edge cloud services from one vendor or different vendors to gain lower distance and reachability to customers for a generic business application while utilizing On-Prem private-cloud solution to host sensitive data due to regulatory obligations.

  3. Mitigating the risk of disaster

Always available, risk free, reliable Operational Environment is the dream and the desire of any organization.
Despite Public or private cloud solutions having their near 100% availability SLA target and guarantee, there is always a risk of outage/failures on any cloud solution, as demonstrated a couple of times by global performance/outage issues of CSPs during the last few years.

Avoiding all the eggs in one basket

In the context of cloud, cost-effectiveness and reliability are tied together. With IT operations, always Single Point-of-Failure to be avoided with high-availability and reliability targets but it should be cost effective too. By setting up optimal RPO (Recovery Point Objective) and RTO (Recovery Time Objective) along with optimal BCP (Business Continuity Planning), an organization can have lower outages.

When an organization is relying on one CSP, the risk of an outage is still higher. To mitigate this risk an organization can choose to have duplicate services across multiple clouds. Will that be actually cost effective? The straightforward answer is NO. It will cost more and more.

The solution is to rely on the optimal operation environment by a mix and match of the services, and workload placement strategy, along with Multi-Cloud orchestration and have Multi-Cloud architecture embedded in the workloads. This will enable the organization to define rules and policies to spin up the workloads in another cloud infrastructure if the primary infrastructure is unavailable. Or they can choose to rely on load balancing across the workload placement in multiple cloud platforms. To achieve any of these, application workloads should be often portable.

  4. Autonomy

The primary directive of moving to the cloud is the ability to run the workloads without locking on the infrastructure. CSPs provide a broad range of services, IaaS, PaaS, CaaS and FaaS however not all the services are commodities.

An organization may choose to migrate to cloud with a single vendor and explore its offerings and use its services in the workloads. When a workload is tied to a certain non-commodity service, it will be difficult to move out.

With a Multi-Cloud approach, an organization can design cloud native, cloud agnostic workloads and place them across multiple CSPs and utilize pick and mix services based on workload requirement. Switching vendors gets easier, simplified and fairly automated at times since workload performance is never tied to individual vendors. With the lower vendor lock-in, an organization gets the autonomy to address changing business needs for performance, security and returns on investments.

Example approach that enables the portability of the infrastructure and workloads.
  • Infrastructure-as-a-Code:
    Treat the provisioning of cloud resources as code which can be deployed, updated and torn upon requirement.
  • Configuration Automation:
    As an Extension to Infrastructure-as-a-Code, provisioned instances may have the automated mutable workload configuration management via configuration automation.
  • Portable Workloads:
    Often containerized workloads are portable across any cloud infrastructure which provides the container runtime. Acting as an immutable infrastructure, workloads will be spun-up and used anywhere which has the required runtime.

  5. Innovation of Public Cloud Service offerings

Public cloud services are aggressively innovative. CSPs release fine tuned, use case optimized services every day and most of the time the customers can utilize these directly in their workloads.

Advanced analytics with the help of AI and ML, Data science tools and platforms, Application integration, Function-as-a-Service offerings are some of the offerings from CSPs other than the IaaS, storage and common services.

Mix and match these offerings from multiple CSPs can be beneficial to an organization to reduce their operational and capital expenditure.

Conclusion

There is no one-fit-all needs cloud solution available for any organization. The multi-Cloud approach is promising to build a cost effective, reliable, optimal and innovative operating environment for the Organization.

However it's not an easy one-day task. To adopt multi-cloud without pitfalls, an organization needs to have a Multi-Cloud strategy which allows them to define and execute the multi-cloud plan across all the aspects of the organization.
