What is multicloud?

Multicloud is a cloud computing strategy that uses the best services from more than one cloud provider to deploy a solution. The strategy is typically driven by workload, business, and data governance requirements. A multicloud solution integrates IaaS, PaaS, and SaaS in a tightly or loosely coupled architecture. A well-designed multicloud solution should consider the network, performance, security, operational management, and total cost of ownership.

Cloud providers often offer managed services and self-service tools to facilitate multicloud delivery. They simplify the design and deployment of multicloud solutions by abstracting the complexity of implementing a particular layer of technology that requires expert knowledge, such as networking.

Multicloud solution patterns

For organizations seeking to optimize cloud infrastructure capabilities and spending, a multicloud solution may be the best approach. It gives organizations access across cloud providers so workloads and data can be placed in an environment best suited to their capabilities. The following solution patterns show how multicloud computing can be used most effectively.

    • Application and database split-stack architecture

      In a multicloud application split-stack architecture, the application front end and database back end are deployed on different clouds with a low-latency and high-bandwidth network connecting the stacks. Organizations can leverage current web or mobile applications to connect to a high-performance database. This architecture leverages best-in-class cloud products and services. The application can be developed with Java, PowerBuilder, Go, .NET, JavaScript, Swift, Kotlin, and other programming languages. The back end can be Oracle Database, a Microsoft SQL Server database, MySQL, and other databases. A dedicated private network connection between the cloud providers is a must-have. Authorized network partners can set it up unless a network cross-connect exists between the cloud providers.

    • Analytics and database split-stack architecture

      In a multicloud analytics split-stack architecture, the data analytics and database are deployed on different clouds with a low-latency and high-bandwidth network connecting the stacks. Organizations can leverage existing data analytics to connect to the database close to the data source. This architecture reduces the logistical complexity and cost of moving around large amounts of data. Microsoft Power BI and Azure Synapse Analytics or Amazon Redshift together with OCI Exadata Database Service or Oracle Autonomous Database is an example. A dedicated private network connection between the cloud providers is recommended unless a network cross-connect exists between the cloud providers.

    • SaaS or ERP data analytics and integration architecture

      In this multicloud architecture, the SaaS or ERP application and the data analytics or custom application are deployed on different clouds with a low-latency and high-bandwidth network connection. The SaaS or ERP is often the mission-critical application of an organization that must be seamlessly integrated with upstream and downstream applications, along with analytics and AI/machine learning (ML). This architecture enables the organization to be flexible to retrofit custom applications and innovate beyond the cloud boundary. An Oracle E-Business Suite, SAP, or Microsoft Dynamics integration with custom applications or a cloud data lakehouse is a good example. A dedicated private network connection between the cloud providers is recommended unless a network cross-connect exists between the cloud providers.

    • Horizontal workload distribution

      A distributed multicloud solution packages the application with or without a database in Kubernetes or virtual machines (VMs). This solution is flexible to run on any cloud. Use cases include on-demand workloads, such as high performance computing (HPC) for animation rendering, artificial intelligence, machine learning, analytics jobs, and video games. PostgreSQL, MongoDB, and MySQL are commonly used if the database is required. The workloads are dynamically distributed horizontally to the Kubernetes clusters or VMs on different clouds based on performance, availability, and cost. A dedicated private network connection or virtual provide network (VPN) between the cloud providers is recommended.

    • Product and development split deployment

      The production and development are deployed in different clouds with a VPN to connect the environments. The organization keeps the current development and testing environment in one cloud while running production in multiple clouds for performance, data residency/proximity, and cost reasons. The workload can be applications. A VPN between the cloud providers is recommended.

Multicloud benefits

The 2022 S&P Global multicloud survey shows that 97% of organizations use more than one cloud provider. According to the survey, the leading factors behind the multicloud approach are cost optimization, data residency, and business agility. A multicloud strategy provides several benefits, including the following:

Cost optimization Data residency Business agility
Best-in-class products and services Regulatory compliance High performance
No vendor lock-in Disaster recovery High availability

A strong provider for your multicloud needs should have the ability to run enterprise workloads while offering flexibility and versatility. This includes operating high-performance workloads or specific database or virtualization stacks. In a best-case scenario, enterprises engaging in a multicloud strategy can optimize service, price, and resources while maintaining flexibility and ensuring data security and interoperability. Getting there takes some considerations, but a multicloud deployment can power an organization’s ability to thrive when done correctly.

Multicloud design considerations

When designing a multicloud solution, it’s essential to consider network latency, data movements, security, orchestration, and operation management, which ultimately drive the architectural decisions.

Latency
Network latency and processing power directly affect application performance. Applications have different latency requirements. Some require very low single-digit milliseconds latency, and others can tolerate double-digit milliseconds latency. Chatty applications such as E-Business Suite, PeopleSoft, JD Edwards EnterpriseOne, Siebel, and Hyperion require optimal low latency—less than two milliseconds—between the application and database. Typically, Java EE and Fusion Middleware applications can tolerate up to 10 milliseconds between the middle tier and the database.

All these applications require a dedicated network connection for consistently low latency. The physical distance of cloud data centers is a factor—they must be within 40 miles. Co-located data centers are the best for these types of workloads. Integrations such as API or database links can tolerate longer latency. The traffic can go over the internet or a virtual private network. In loosely coupled architecture, the physical distance of cloud data centers is less critical.

Data movements
If large-scale data is transferred across the cloud boundary frequently, the direction of data flow becomes essential. Cloud providers typically don’t charge data ingress, but all charge a data egress fee. The data egress rates vary among cloud providers. It’s crucial to take egress cost into multicloud design considerations. In addition, data residency must be considered when moving data. For example, the EU General Data Protection Regulation requires all EU data to remain within European Union countries. Some industries—including telecommunications; manufacturing; healthcare; insurance; and software, IT, and computer services—have stringent data locality requirements.

Security
In a multicloud environment, disparate security tools and multiple vendors can result in complex security operations and increased security headcount, leading to costly inefficiencies, ineffectiveness, and unnecessary security risk. As organizations reevaluate their technology stack to strengthen their cybersecurity and improve agility, scalability, and efficiency, they’re seeking cloud providers that offer products and services with built-in security and the ability to integrate with third-party vendors seamlessly. A layered security strategy can simplify the approach by using built-in cloud security services offered by the cloud provider combined with prebuilt APIs and cloud provider partnerships that integrate providers and common event models to process alerts at scale.

Orchestration
How you deploy and manage the multicloud architecture matters. Each cloud has its own set of tools and workflows. That puts tremendous pressure on IT teams to be experts in various technologies. Choosing automation tools to work across clouds is essential. Automated tools are available for networking, security, continuous integration, and continuous delivery (CI/CD). Infrastructure as code, for example, is essential to maximizing availability, scalability, flexibility, and cost optimization. At the same time, security tools are crucial to zero-trust security implementation, access controls, and session management.

An automation tool is a critical component in multicloud deployment and operation management. When choosing an automation tool, you should consider your current on-premises technology stacks, tools, and IT team skillsets. The tool should work in multicloud and hybrid cloud environments. Adding it into workflows usually requires your most skilled personnel.

Operation management
Operation management includes support access, monitoring and alerting, patching updates, regulatory compliance, and governance. Establishing standard practices and procedures across cloud platforms is vital. Standardizing the cloud operating model can help organizations efficiently address the multicloud barriers around people, processes, and tools; doing so is essential for productivity, ongoing security, consistency, and faster incident resolution. For example, support personnel use a single sign-on (SSO) account and access point to access all clouds, alert auto-ticketing, and integrate with one ticketing system.
