Multicloud

What is multicloud?

There are variations between multicloud and hybrid cloud service deployment and management:

• Multicloud: Multicloud refers to using multiple cloud computing and storage services within a single network architecture. Workloads are distributed among public clouds, private clouds, or both under this technique. Each cloud service provider has different features, prices, and geographies. Organizations use multicloud to prevent vendor lock-in, increase redundancy, maximize performance, and use services from different providers. 
• Hybrid cloud: This computing environment allows data and programs to be exchanged between public and private clouds. A hybrid cloud system utilizes a combination of private and public cloud architectures to host resources and workloads. The hybrid cloud architecture offers flexibility, scalability, and security by keeping sensitive data and important apps on-premises and using the public cloud for other workloads.

In conclusion, hybrid cloud integrates public and private cloud environments to build a cohesive architecture, whereas multicloud uses numerous cloud services from different providers.

There are pros and cons to using a multicloud strategy. The following are some advantages and disadvantages:

• Complex Vendor Management: Multiple cloud providers need contract negotiation, SLAs, and continuous relationship management.
• Multicloud strategies offer flexibility and resilience, but enterprises have to evaluate the trade-offs and invest in the resources and knowledge to manage and optimize their multicloud systems.

Assessment and Planning:

• Detailed Assessment: Assess your IT infrastructure, including applications, workloads, data, and dependencies.
• Workload Analysis: Determine workloads by performance, scalability, regulatory compliance, and data sensitivity.
• Multicloud Suitability: Based on cloud compatibility, portability, and strategic relevance, choose workloads for multicloud deployment.

Selecting and Integrating Vendors:

• Provider Selection Criteria: Select cloud providers based on regional availability, service offerings, pricing models, performance, dependability, security, and compliance certifications.
• Seamless Integration: Use cloud providers with suitable services and APIs for seamless integration. Standardize deployment and administration across various clouds with Kubernetes, Terraform, and API gateways.

Monitoring and Optimization:

• Continuous Monitoring: Track performance, resource consumption, expenses, and security across all cloud environments with powerful monitoring solutions.
• Optimization Strategies: Monitor resource allocation, instance sizing, and use trends to enhance efficiency and cost-effectiveness. Auto-scaling, rightsizing, and workload allocation may match resource provisioning with workload needs.

Best practices for multicloud infrastructure help businesses achieve goals and minimize risks.

The use cases and scenarios where numerous cloud providers offer advantages drive multicloud adoption. Here are some multicloud use cases and examples:

Risk Mitigation and Redundancy:

• Use Case: To reduce the risk of vendor lock-in, service interruptions, or data loss, workloads can be divided among several cloud providers.
• Example: A financial institution uses multiple cloud platforms to ensure the high availability and resilience of its vital apps and data. To ensure company continuity, services can smoothly switch cloud providers during outages.

Geoflexibility and Compliance:

• Example: Deploying resources across several countries to meet data residency laws, minimize latency, and increase global user performance.
• Example: An e-commerce firm uses cloud providers to host apps and data centers in data protection zones across countries. By dispersing resources across numerous clouds, the firm delivers low-latency global experiences while ensuring compliance.

Service Diversity and Specialization:

• Use Case: Employing cloud providers' specialized services and capabilities to satisfy corporate needs or maximize performance.
• Example: A financial institution utilizes HPE GreenLake for on-premises infrastructure, HPE Ezmeral for container orchestration, and HPE Cloud Volumes for data storage. Multicloud enables the organization to leverage HPE's diverse product offerings for enhanced performance, scalability, and data management across different aspects of its operations. 

Cost Optimization and Flexibility:

• Use Case: Optimizing expenses using cloud provider discounts, promotions, and price variants.
• Example: A SaaS business can save on cloud spending by using reserved instances or committed use discounts for application components. 

Hybrid Cloud Integration:

• Use Case: Integrating on-premises infrastructure with public cloud services for hybrid cloud deployments, scalability, and capability.
• Example: A manufacturer uses public cloud services for agility and stores sensitive data on-premises. A multicloud solution combines on-premises systems with cloud providers to create a hybrid cloud architecture.

These examples highlight how a multicloud approach may help companies achieve their goals efficiently, effectively, and securely.

Private cloud governance ensures cloud resources are used effectively, safely, and in accordance with business regulations. Key responsibilities include:

• Policy enforcement: Setting and implementing cloud resource use policies to ensure corporate and regulatory compliance.
  
• Compliance management: Ensuring the private cloud fulfills data protection and privacy laws and other legal, regulatory, and industrial requirements.
  
• Resource management: Allocating and using cloud resources to meet company goals and avoid waste.
  
• Risk management: Assessing and managing cloud operations risks such security vulnerabilities and operational hazards.
  
• Cost control: Tracking cloud expenditures to avoid budget overruns and assure corporate priorities.
  
• Performance monitoring: Monitoring cloud resources and services to satisfy standards and goals.
  

Governance balances operational efficiency, security, and compliance in private cloud settings.

Multicloud environments provide several advantages, but their real value depends on an organization’s goals. Potential advantages include greater flexibility, risk mitigation, access to expensive technology without the capital expenditure, high availability, and more. Each is covered in detail below:

• Flexibility: A flexible modular infrastructure helps companies develop software faster, adjust quickly to changing demand, and only pay for what they consume. It also allows companies to take advantage of technology advances rapidly, select different vendors to combine services, and create applications that are more custom and provide competitive advantage.
• Resiliency: By using multiple clouds, companies have limited exposure to just one vendor, which reduces the risk of outages/security failures. When one cloud fails, services from other providers can still run, keeping your business in operation. With such redundancies, organizations have an always-on, highly scalable backup for data, workflows, and systems.
• Costs: By using resources as a service, companies can avoid capital expenditures and increased staff count to reduce the cost of data management. And with providers absorbing the cost of maintenance and upgrades, an enterprise can focus more resources to deliver new/more products and services to customers without increasing personnel to manage them.
• Availability/performance: Once a new solution/service is identified, a cloud provider can get it up and running almost instantly, compared to longer on-premises timelines. Also, deploying workloads on clouds closer to where users reside can maximize response times and maintain high availability.
• Innovation: With a multicloud environment, enterprises can develop new and enhanced products and services, create innovative business models, and create new revenue streams.
• Data sovereignty: Regulations, laws, and corporate policies can require data to physically reside in a given region or country. Organizations can use a multicloud solution to locate data storage within the areas being regulated.
