Today's cloud ecosystem features a variety of cloud strategies designed to suit different organizational needs. The evolution of cloud computing has transformed from single-vendor solutions to more complex, integrated approaches that leverage multiple providers. Despite the trend to move to the cloud, it's rare for enterprises to deploy 100% of their applications in a single cloud environment.
Many organizations want the freedom to invest in their cloud future by seamlessly and securely developing and deploying applications across different public clouds. This shift toward multicloud environments reflects the maturing understanding that no single cloud provider can optimally address all business requirements.
Current trends show that approximately 79% of companies are taking advantage of multicloud facilities, recognizing that a diversified approach helps build portable software stacks that are DevOps-driven, vendor lock-in-free, and capable of delivering suitable services for specific business needs.
Understanding Cloud Models
What is MultiCloud?
Multicloud refers to the use of multiple cloud computing services from different providers to serve an organization's IT services and infrastructure. In a multicloud environment, there is no single vendor. Instead, it's a mixture of major public cloud providers, namely Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and IBM.
Fig 1: MultiCloud
Multicloud is primarily a strategy that uses several different architectures, such as Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS), to achieve business goals. It focuses on various providers to address specific workload requirements but doesn't necessarily require connectivity.
MultiCloud Strategy Example
An e-commerce company might adopt a multicloud strategy as follows:
-
AWS is used to host its website and handle customer traffic.
-
Store customer transaction data on Google Cloud for real-time analytics.
-
Use Azure AI for personalized product recommendations.
-
Maintain disaster recovery backups in IBM Cloud for redundancy.
What is Hybrid Cloud?
A hybrid cloud is an infrastructure model that connects at least one public and one private cloud. It combines on-premise infrastructure, public cloud, and private cloud with orchestration among numerous platforms.
Fig 2: Hybrid Cloud
To establish a hybrid cloud, organizations need:
- Public Infrastructure as a Service (IaaS) platform, such as AWS, Microsoft Azure, or Google Cloud
- Construction of a private cloud, either through a hosted private cloud provider or on-premises
- Adequate wide area network connectivity between the environments
This model enables customers to have functional advantages such as application portability according to cost and need and management control to develop a single, flexible, and optimal cloud environment based on the organization's needs.
What is Hybrid MultiCloud?
Hybrid multicloud occurs when an organization uses multiple public cloud services in its solution, often from multiple different providers, while also maintaining private cloud or on-premises infrastructure. This approach allows organizations to use different clouds for various tasks to achieve best-of-breed results or reduce vendor lock-in.
Fig 3: Hybrid MultiCloud
Multiple clouds also give organizations peace of mind by minimizing dependence on any one provider, often decreasing costs and increasing flexibility. A hybrid multicloud environment allows for distributing various cloud software and applications across several cloud environments.
What is a Private Cloud?
A private cloud, more commonly known as an internal or corporate cloud, is a cloud infrastructure explicitly provided for a single customer. It's an isolated, on-demand cloud deployment model with its own cloud computing services and infrastructure hosting. These don't necessarily have to be deployed on-premises and can be managed through a service provider agreement.
Fig 4: Private Cloud
According to the National Institute of Standards and Technology, a private cloud must:
- Provide on-demand self-service computing resources
- Enable and make resources accessible from multiple types of devices
- Pool resources and allow serving them in a multi-tenant fashion
- Have the ability to automatically and elastically scale resources
- Evaluate and measure the use of resources by various consumers
