Choosing a Hybrid cloud offering
April 14, 2023
Introduction
A hybrid cloud combines an on-premises datacenter (also called a private cloud) with a public cloud, allowing data and applications to be shared between them.
Grep Digital has come across this requirement in recent digital transformation efforts, where there was need for datacentre elasticity which the existing customer infrastructure did not support. Instead of expanding the customer infrastructure, a hybrid cloud approach was suggested. This article explores key factors to consider when selecting the ideal hybrid cloud solution to propel your business into a successful digital future.
Types of Hybrid Cloud Offerings
Organizations can choose from various hybrid cloud options, including cloud bursting, data tiering, cloud-native hybrid, and disaster recovery (DR). Cloud bursting supports peak demand by switching to public cloud during spikes while maintaining a private or on-premises setup. Data tiering segregates less sensitive data to the public cloud while securing sensitive data on-site. Cloud-native hybrid allows cross-environment application development, leveraging public and private cloud strengths. Disaster recovery (DR) safeguards critical data and apps in a public cloud backup site. These options offer flexibility, scalability, and legacy system integration to optimize infrastructure for unique needs.
Let’s understand the different type of clouds in more detail.
Cloud Bursting
Cloud bursting is a specific type of hybrid cloud offering that allows organizations to handle spikes in demand by utilizing a private cloud or on-premises infrastructure as their primary environment, but seamlessly scaling into a public cloud during peak load periods. Here’s a more detailed explanation:
1. Scalability on Demand
Cloud bursting provides organizations with the ability to scale their infrastructure dynamically in response to fluctuating demand. During normal operations, organizations utilize their private cloud or on-premises infrastructure to handle their workload requirements. However, when there is a sudden surge in demand or peak load periods, the organization can seamlessly “burst” into a public cloud environment to supplement their resources and accommodate the increased workload. This scalability on demand ensures that organizations can effectively handle spikes in traffic, maintain performance, and meet customer expectations without overprovisioning their private infrastructure.
2. Resource Optimization
Cloud bursting enables organizations to optimize their resource allocation. Instead of investing heavily in on-premises infrastructure to accommodate occasional peaks in demand, organizations can rely on the public cloud to scale up their resources only when needed. This approach helps reduce infrastructure costs by allowing organizations to pay for additional capacity on a temporary basis, aligning costs with actual resource usage. By optimizing resource allocation, organizations can achieve cost-efficiency and avoid the waste of maintaining idle resources during periods of lower demand.
3. Seamless Scalability
One of the key advantages of cloud bursting is its seamless scalability. The transition from the private cloud or on-premises environment to the public cloud occurs transparently to end-users and applications. When the workload surpasses the capacity of the private infrastructure, the bursting mechanism automatically provisions resources in the public cloud to accommodate the increased demand. This seamless scalability ensures uninterrupted service delivery, consistent user experience, and business continuity during peak load periods.
4. Load Balancing and Performance Optimization
Cloud bursting allows organizations to balance the workload across multiple environments to optimize performance. During peak load periods, bursting distributes the excess workload to the public cloud, which typically offers extensive compute and storage capacity. This load balancing mechanism helps organizations maintain optimal performance levels by leveraging the resources of both the private and public cloud environments. It ensures that the workload is distributed efficiently and processed in a timely manner, preventing performance bottlenecks and enhancing the user experience.
5. Cost Control and Pay-as-You-Go Model
Cloud bursting aligns with a cost control approach by enabling organizations to optimize costs through a pay-as-you-go model. During normal operations, organizations primarily utilize their private cloud or on-premises infrastructure, which often represents a fixed cost. However, during peak load periods, organizations can leverage the public cloud resources on a temporary basis, paying only for the additional capacity used. This cost-effective approach helps organizations avoid the need for extensive capital expenditures, optimize operational expenses, and ensure cost efficiency by scaling resources in a cost-conscious manner.
6. Data and Application Consistency
Cloud bursting ensures data and application consistency across both the private and public cloud environments. Organizations can replicate data, synchronize databases, and implement mechanisms to maintain consistency between the two environments. This ensures that data integrity is preserved, and applications can seamlessly operate across both the private and public cloud components without disruptions. Consistent data and application states are critical for maintaining business operations and providing a seamless user experience during the bursting process.
Data Tiering
The data tiering aspect of hybrid cloud offerings involves the strategic placement of data based on its sensitivity, criticality, and access patterns. Organizations can store less sensitive or non-critical data in the public cloud. All these while keeping sensitive or critical data in a private cloud or on-premises infrastructure. The detailed explanation follows:
1. Data Segmentation
Data tiering enables organizations to segment their data based on its characteristics and requirements. By categorizing data into different tiers, organizations can apply different storage and management policies. This is based on factors such as sensitivity, criticality, and access patterns. This segmentation ensures that data is appropriately protected and managed, aligning with security and compliance requirements.
2. Security and Compliance
The data tiering approach helps organizations address security and compliance concerns. Sensitive or critical data can be stored in a private cloud or on-premises infrastructure. This is applicable where organizations have greater control over security measures and compliance requirements. This ensures that sensitive data remains protected and complies with industry regulations or internal policies. Less sensitive data can be stored in the public cloud, leveraging the security measures provided by the cloud service provider. This allows to adhere to applicable data protection regulations.
3. Cost Optimization
Data tiering offers cost optimization benefits by aligning storage costs with the value and sensitivity of the data. Public cloud storage is more cost-effective for non-critical data due to its scalability and pay-as-you-go pricing model. By utilizing the public cloud for such data, organizations can optimize storage costs. Critical or sensitive data stored in private clouds or on-premises infrastructure may incur higher costs. But it provides organizations with greater control, security, and compliance capabilities.
4. Performance and Access Patterns
Data tiering allows organizations to optimize performance by aligning data storage with access patterns. Frequently accessed data or data required for real-time processing can be stored in the private cloud or on-premises infrastructure. This ensures low-latency access and optimal performance. Less frequently accessed or archival data can be stored in the public cloud. The retrieval times and performance requirements for such data are typically less critical.
5. Data Movement and Synchronization
Data tiering involves the movement of data between different tiers based on changing access patterns, security requirements, or business needs. Organizations can implement data management and migration mechanisms that facilitate seamless movement of data between the private and public cloud. This ensures data consistency, minimizes disruptions, and provides a unified view of data across the hybrid cloud environment.
6. Data Lifecycle Management
Data tiering is often coupled with data lifecycle management strategies. Organizations can define policies that determine the lifecycle of data, including storage duration, archiving, and eventual deletion.
