How to choose the right multi-cloud strategy for your organization

Are you looking to adopt a multi-cloud strategy for your organization? Congratulations! You are making a wise decision that can bring many benefits, such as increased performance, availability, scalability, and cost-effectiveness. But how do you choose the right multi-cloud strategy that meets your specific needs, goals, and constraints? In this article, we will guide you through the key considerations and trade-offs involved in selecting a multi-cloud approach that works best for you.

What is multi-cloud?

Before we dive into the details, let's first define what we mean by multi-cloud. Simply put, multi-cloud is the use of multiple cloud computing services from different providers, such as Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), IBM Cloud, Oracle Cloud, and more. Multi-cloud can be used for various purposes, such as avoiding vendor lock-in, enhancing redundancy and resilience, optimizing pricing and features, complying with regulations, and leveraging the strengths of different clouds for different workloads.

Why choose multi-cloud?

The reasons for choosing multi-cloud can vary depending on your organization's priorities, such as:

• Flexibility: Multi-cloud allows you to use different clouds for different purposes, such as running development and testing environments on one cloud, production environments on another cloud, and disaster recovery on a third cloud.
• Cost savings: Multi-cloud can help you optimize your costs by choosing the right cloud for the right job, such as using a cheaper cloud for non-critical workloads or using a cloud with a better pricing model for your usage patterns.
• Innovation: Multi-cloud can enable you to leverage the latest and greatest technologies and services from different clouds, such as AI/ML, IoT, blockchain, and more, without being limited by one cloud's offerings.
• Compliance: Multi-cloud can help you meet your regulatory and security requirements by using clouds that comply with different standards and certifications, such as HIPAA, PCI, ISO, and SOC.
• Business continuity: Multi-cloud can enhance your resilience and uptime by distributing your workloads across different clouds, regions, and availability zones, and avoiding single points of failure.

What are the types of multi-cloud?

When it comes to multi-cloud, there are several types or patterns that you can choose from, depending on your needs and preferences. Let's take a look at the main types of multi-cloud and their characteristics.

Deployment multi-cloud

Deployment multi-cloud is the use of multiple clouds to deploy the same application or workload, either for redundancy or for performance optimization. Deployment multi-cloud can be achieved in several ways, such as:

• Active-active: This approach involves running the same application or workload concurrently on two or more clouds, and load balancing the traffic between them. This can provide high availability and fault tolerance, but may also incur higher costs and complexity.
• Active-passive: This approach involves running the same application or workload on one cloud as the primary site, and replicating the data and configuration to another cloud as the secondary site. In case of a failure or outage in the primary site, the secondary site can take over and resume the service.
• Bursting: This approach involves using one cloud as the primary site for normal usage, and using another cloud as a burst site for peak demand or overflow. This can help you avoid overprovisioning and paying for unused capacity, but may require careful planning and coordination.

Data multi-cloud

Data multi-cloud is the use of multiple clouds to store, process, and manage different types of data, either for compliance or for performance optimization. Data multi-cloud can be achieved in several ways, such as:

• Replication: This approach involves replicating the data from one cloud to another cloud, either synchronously or asynchronously, for backup, DR, or data sharing purposes. Replication can ensure data consistency and availability, but may also incur additional storage costs and network bandwidth.
• Federation: This approach involves keeping the data on each cloud as a separate partition or zone, and using a common interface or API to access and manage the data across clouds. Federation can provide scalability and flexibility, but may also require a common data model and governance.
• Tiering: This approach involves storing different types of data on different clouds based on their access frequency, lifespan, sensitivity, or cost. For example, you can store cold data on a cheaper cloud, warm data on a faster cloud, and hot data on a cloud with low latency and high throughput.

Application multi-cloud

Application multi-cloud is the use of multiple clouds to host different components or services of the same application, either for horizontal scaling or for feature optimization. Application multi-cloud can be achieved in several ways, such as:

• Microservices: This approach involves breaking down the application into multiple small and independent services, and deploying each service on the cloud that suits it best, based on its resource requirements, dependencies, and functionality. Microservices can enable agility, resilience, and innovation, but may also require a complex architecture and testing.
• Containers: This approach involves packaging each service as a container image, and running the container on any cloud that supports the container runtime, such as Kubernetes. Containers can provide portability, consistency, and efficiency, but may also require expertise in containerization and orchestration.
• Hybrid cloud: This approach involves hosting some parts of the application on-premises or in a private cloud, and hosting other parts on public clouds or SaaS providers. Hybrid cloud can provide a balance between control, security, and cost, but may also require integration and management challenges.

Management multi-cloud

Management multi-cloud is the use of multiple clouds to manage, monitor, and govern your cloud deployments, either for automation or for compliance. Management multi-cloud can be achieved in several ways, such as:

• Orchestration: This approach involves using a cloud-agnostic orchestration platform, such as Terraform, Ansible, or CloudFormation, to deploy and manage your workloads across multiple clouds. Orchestration can provide consistency, repeatability, and auditability, but may also require a learning curve and compatibility issues.
• Cloud management platform: This approach involves using a third-party cloud management platform, such as CloudHealth, Cloudyn, or CloudMGR, to monitor, optimize, and govern your cloud usage across multiple clouds. Cloud management can provide insights, recommendations, and automation, but may also require additional costs and dependencies.
• Governance and compliance: This approach involves using a combination of policies, controls, and audits to ensure that your cloud usage across multiple clouds complies with your internal and external regulations and standards. Governance and compliance can provide assurance, transparency, and risk mitigation, but may also require a complex and dynamic framework.

How to choose the right multi-cloud strategy?

Now that we have explored the main types of multi-cloud and their characteristics, you may wonder which one is the right fit for your organization. The truth is, there is no one-size-fits-all answer, as each organization has its own unique set of requirements, constraints, and culture. However, there are some guiding principles and best practices that can help you make an informed decision about your multi-cloud strategy.

Know your goals and priorities

The first step in choosing the right multi-cloud strategy is to know your goals and priorities, and align them with your stakeholders and decision-makers. Some questions that can help you clarify your goals and priorities are:

• Why do we need multi-cloud?
• What are the benefits we expect from multi-cloud?
• What are the risks and challenges we foresee with multi-cloud?

The second step in choosing the right multi-cloud strategy is to assess your workloads and data, and classify them based on their requirements, dependencies, and priority. Some factors that can influence your workload and data classification are:

• Resource demand: How much CPU, RAM, storage, and network bandwidth does each workload or data type require?
• Performance objectives: What are the latency, throughput, and availability requirements for each workload or data type?
• Data sensitivity: What are the security, privacy, and compliance requirements for each data type?
• Data access: Who needs to access, manipulate, and analyze each data type, and from where?
• Data lifecycle: What are the retention, archiving, and deletion policies for each data type?
• Workload dependencies: What are the dependencies, integrations, and interfaces among your workloads, and how can they be decoupled or modularized?

By classifying your workloads and data, you can identify the opportunities and challenges of using multi-cloud for each type, and prioritize your adoption roadmap based on the criticality, feasibility, and impact of each use case.

Evaluate your cloud providers

The third step in choosing the right multi-cloud strategy is to evaluate your cloud providers, and compare their strengths, weaknesses, and trade-offs. Some criteria that can help you evaluate your cloud providers are:

• Cloud services: What are the services and features that each cloud provider offers, such as compute, storage, networking, database, app development, analytics, security, and compliance?
• Cloud performance: What are the performance metrics and benchmarks that each cloud provider provides, such as CPU, RAM, IOPS, latency, throughput, and uptime?
• Cloud security: What are the security controls and certifications that each cloud provider offers, such as encryption, access management, vulnerability scanning, and compliance reporting?
• Cloud pricing: What are the pricing models and discounts that each cloud provider provides, such as on-demand, reserved, spot, or prepaid instances, and how do they vary across regions, usage patterns, and workloads?
• Cloud ecosystem: What are the partner and third-party solutions and integrations that each cloud provider supports, such as marketplaces, APIs, dev tools, and management consoles?
• Cloud support: What are the support options and SLAs that each cloud provider offers, such as self-service, standard, premium, or enterprise support, and how responsive and effective are they?

By evaluating your cloud providers, you can identify the strengths and weaknesses of each one, and choose the right mix of clouds for your multi-cloud strategy, based on your workload and data requirements, as well as your budget, skills, and preferences.

Define your governance and management model

The fourth step in choosing the right multi-cloud strategy is to define your governance and management model, and establish the policies, practices, and tools that will ensure the compliance, security, efficiency, and agility of your multi-cloud environment. Some aspects that you should consider when defining your governance and management model are:

• Cloud architecture: What are the patterns, standards, and best practices for designing your multi-cloud architecture, such as using common API gateways, consistent naming conventions, and federated identity and access management?
• Cloud monitoring: What are the metrics, logs, and alerts that you need to monitor and measure your multi-cloud performance, security, and compliance, and what are the tools and dashboards that you will use to visualize and analyze them?
• Cloud automation: What are the tasks, workflows, and processes that you can automate and optimize in your multi-cloud environment, such as provisioning resources, deploying applications, scaling workloads, and enforcing policies, and what are the tools and scripts that you will use to do that?
• Cloud integration: What are the integration points and protocols that you need to enable in your multi-cloud environment, such as API gateways, messaging queues, event streams, and data pipelines, and what are the tools and adapters that you will use to facilitate them?
• Cloud governance: What are the policies, controls, and audit trails that you need to establish and enforce in your multi-cloud environment, such as security policies, compliance rules, cost allocation, and service level agreements, and how do you ensure that they are followed and verified?

By defining your governance and management model, you can ensure that your multi-cloud environment is well-architected, well-monitored, well-automated, well-integrated, and well-governed, and that your stakeholders and decision-makers have the visibility, control, and confidence they need to manage and optimize your multi-cloud investments.
