The role of automation in multi-cloud operations

If you're managing an enterprise's cloud operations, chances are you're working with more than one cloud service provider. Gone are the days of a single cloud environment - today, businesses require the flexibility of multi-cloud operations to maximize availability, minimize costs and remain agile in a constantly evolving landscape. However, with multiple clouds comes increased operational complexity and an exponentially growing need for automation.

Let's dive into the role that automation plays in multi-cloud operations.

The challenge of managing multiple clouds

With a single cloud environment, managing cloud operations might not be too difficult. However, with each additional cloud added into the mix, complexity increases. The resulting complexity can cause a variety of issues, including increased security risks, misconfigurations, and slower overall performance.

Ensuring that multiple clouds are properly configured and working together in harmony is critical. Multi-cloud operations management covers a range of tasks, including:

• Provisioning resources and applications
• Monitoring and alerting for performance and availability
• Security and compliance management
• Backup and disaster recovery
• Governance and cost management

Conventional manual or semi-manual management is not scalable, and can create significant risk of human error, downtime, or data leakage.

Here's where automation comes in.

Automation in multi-cloud operations: the benefits

Automation can reduce the complexity and risks associated with managing multiple clouds. It enables you to streamline processes, minimize human errors, and optimize efficiency across your entire infrastructure.

With automation, you can achieve:

Increased scalability

Automation enables multi-cloud operations to scale alongside the amount of services being used. Managing a single cloud system manually can be manageable, but as your cloud environment grows, so does the complexity of the task.

Improved security and compliance

Automating security management allows for quicker identification of security vulnerabilities and faster remediation. Automation can also help ensure that compliance requirements are met across all cloud environments.

Greater speed and accuracy

By automating many of the traditionally manual or semi-manual processes, IT teams can respond faster to incidents, and also reduce the time required for new service and application deployments.

Cost optimization

Automation can help businesses optimize their cloud usage and expenditure by reducing waste, increasing utilization, and helping predict future costs more accurately.

Automated multi-cloud architecture

By automating multi-cloud architecture design, it's possible to deliver a managed multi-cloud solution that addresses common multi-cloud challenges. This means that instead of relying on a single cloud service provider, businesses can use a range of providers in order to build resilient, hybrid environments.

In order to achieve the benefits of automation, businesses must implement a reliable, scalable multi-cloud architecture that allows for standardization of existing services and applications across all cloud providers.

One such tool for automating multi-cloud operations is Terraform. Terraform is an open source tool by HashiCorp that offers a standard way of describing infrastructure across multiple cloud platforms. With Terraform, IT teams can create graphical representations of their infrastructure in the form of 'Plans', then automate deployment, maintenance, and monitoring across multiple clouds at once.

Challenges of automation in multi-cloud operations

While automation in multi-cloud environments can offer numerous benefits, there are still some challenges that businesses should be aware of.

Complexity

Automation can make cloud management simpler, but managing an automated infrastructure can be complex in itself. A multi-cloud environment may require automation processes with several components that interact together, making it difficult to manage, and requiring careful attention to ensure that it performs as intended. Automation code can also be complex, and must be tested frequently to ensure it continues to perform correctly after updates or changes.

Cloud provider integration

It's no secret that every cloud provider is different. This is true not only in terms of pricing, security and performance characteristics, but also API functionality, and other operational aspects. As a result, automation tools must balance each provider's idiosyncrasies in order to integrate them properly into the automation process.

Security

Automation introduces another layer of security concerns. A mistake in automation code could inadvertently grant access to sensitive data or resources. Security and policy enforcement must therefore remain a top priority in automated multi-cloud operations management.

Resource constraints

Automation usually comes at a price - complex automation processes can be resource-intensive and can consume significant amounts of CPU and/or memory resources, which can impact both cloud service performance and resource costs. IT teams should document their "minimum build" requirements before embarking on an automation project and ensure that they have the resources available to run them.

Summary

Multi-cloud operations for enterprises is a necessary component of IT infrastructure, but managing multiple clouds can be a daunting task. Automation can help solve the challenges of managing multiple clouds, from security and compliance to optimization of cloud spend. While there are some challenges to automation in multi-cloud operations, it's clear that the benefits of automation far outweigh the risks.

Terraform provides a comprehensive open source solution for automating multi-cloud operations, offering a standardized cross-platform approach, and allowing for graphical representations of multiple cloud infrastructure.

Going forward, businesses must keep in mind the complexities of this approach, as well as the human and resource requirements, but it's clear that automation is a necessary step for successful multi-cloud operations.
