The hybrid cloud approach is becoming increasingly popular because it offers a balanced solution addressing the limitations of traditional on-premises infrastructure and the challenges of relying solely on public or private clouds. It empowers companies to harness the benefits of both worlds, providing flexibility, scalability, cost efficiency, and enhanced security to meet the demands of the modern digital era effectively.
However, organizations need to have a strategy in place to effectively implement and manage a hybrid cloud infrastructure. In this blog, we will learn about those strategies and the challenges one might face while implementing them.
A hybrid cloud is a cloud computing model that combines the use of both public and private clouds, allowing data and applications to be shared between them. In a hybrid cloud environment, an organization typically maintains a private cloud infrastructure while also utilizing resources from a public cloud provider, such as Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), or others. These two cloud environments are connected in a way that allows data and applications to be seamlessly moved between them.
To ensure a successful cloud deployment, you need to have a well-thought-out plan for migrating the on-premises or co-located application workloads and their associated data to the cloud. Your migration plan should consist of a comprehensive plan that outlines the entire migration process.
Besides that, also assess what preparations are required before the actual migration begins, such as any necessary adjustments to your applications or data. Proceed to design the migration plan, ensuring that all aspects are meticulously mapped out in your next step.
To minimize risks and identify potential issues, it's advisable to conduct a pilot project as part of your plan.
When reviewing the infrastructure currently in place before migration, it's crucial to consider any interdependencies that might exist between different workloads. Consider not only the individual requirements of these workloads but also their placements within your IT ecosystem to ensure they continue functioning seamlessly. By understanding the intricate connections and dependencies, you can plan a migration strategy that minimizes disruptions and maintains the overall stability of your IT environment.
Security is of utmost importance in your strategy planning for hybrid cloud adoption. Thus, it should be seen as a collective responsibility that extends to everyone interacting with your sensitive data, workloads, and overall infrastructure.
To ensure security, consider aspects like software-defined networking (SDN), virtualization, and application support as a part of your strategy. These security measures must include data centers and hardware devices to ensure a comprehensive and robust defense against potential threats.

Ensure that clouds collaborate seamlessly instead of operating in isolation by crafting the right strategy. This makes sure that different cloud environments communicate effectively with one another, pooling their capabilities to collectively achieve your desired objectives of migrating to a hybrid cloud.
Evaluate the hybrid cloud platforms available and select the one that aligns best with the level of compliance your organization requires for each workload. Alternatively, consider enlisting the expertise of a compliance expert who can help ensure that your organization holds the necessary certifications and meets the regulatory standards applicable to your industry. By taking these steps, you can confidently navigate the complexities of compliance and ensure that your cloud infrastructure meets all the necessary regulatory criteria.
Prepare a disaster recovery plan specific to geography and potential vulnerabilities that may or may not arise from natural disasters, human error, or cybercrime. The more comprehensive your disaster recovery plan is, the more effectively you'll be able to ensure the continuity of your business operations in case an unforeseen event disrupts them.
Once you've completed the cloud migration process, it's crucial to focus on cleaning up any connections or systems that are no longer necessary. Ensuring a tidy environment helps streamline your hybrid cloud infrastructure. Furthermore, everything that has been moved to the cloud should be optimized for efficiency, secured to safeguard your data, and made easily retrievable for smooth operations.
To manage your hybrid cloud effectively, it's wise to have a dedicated team in place. This team should be well-prepared to handle both day-to-day operations and emergencies. You can assemble this team using in-house experts, engage outsourced providers, or even opt for a combination of both approaches. Having the right team ensures that your hybrid cloud environment runs smoothly and is ready to respond effectively to any challenges that may arise.
Organizations looking to migrate their applications and workloads to the cloud should work on the Seven R’s framework of cloud migration. This is a methodology that helps organizations make informed decisions about which applications to migrate, how to migrate them, and what to do with applications that may not be suitable for migration. Here's an elaboration of each of the seven Rs:
Identify and discontinue applications that are no longer needed within your organization's IT ecosystem. These are typically legacy applications or redundant systems that can be safely decommissioned. By retiring such applications, you can reduce the complexity of your hybrid cloud environment, free up valuable resources, and streamline your cloud migration efforts, ensuring that only essential workloads are hosted in the hybrid cloud.
Recognize applications that, for various reasons such as compliance requirements or data sensitivity, must remain on-premises or within a private cloud environment. These applications may not be suitable for migration to the public cloud, but it's crucial to ensure they continue to operate effectively. By retaining these applications in a private cloud or on-premises environment, you can maintain control over critical business functions while still benefiting from hybrid cloud capabilities for other workloads.
Evaluate custom or legacy applications within your organization that can be substituted with off-the-shelf software or Software as a Service (SaaS) solutions available in the cloud marketplace. Replacing applications in this manner can lead to cost savings, reduce the burden of maintaining custom software, and streamline your hybrid cloud environment by incorporating standardized cloud solutions where applicable.
Migrate existing applications to the cloud without making significant changes to their architecture or code. This is often referred to as "lift and shift." Rehosting allows you to take advantage of the scalability and cost-efficiency of public cloud resources while maintaining the existing functionality of your applications, making it a relatively quick and straightforward migration option.
Make minor adjustments or optimizations to applications to make them more compatible with the cloud environment. This approach is chosen when migrating applications to the cloud while recognizing the potential for performance improvements, cost savings, or better resource utilization. Replatforming aims to enhance an application's ability to leverage cloud services and resources efficiently.
Make significant modifications to an application to align it with cloud-native principles and microservices architecture. This approach is chosen when an application needs extensive redevelopment to fully utilize the benefits of cloud resources, such as scalability and flexibility. Refactoring can lead to improved performance, agility, and the ability to take full advantage of the hybrid cloud's capabilities.
It is the highest level of transformation in a hybrid cloud strategy. It involves completely rethinking an application's design and architecture to be cloud-native and microservices-based. This approach aims to maximize the business value and innovation potential offered by the hybrid cloud. By reimagining applications, organizations can achieve the highest level of agility, scalability, and efficiency, driving business growth and competitiveness through cloud-native technologies.
Though the above-mentioned strategy for hybrid cloud adoption will help you greatly, there could be some challenges in the path.
Undoubtedly, there would be some sort of legacy dependencies that you may overlook while introducing new cloud resources and services. They should be taken into account otherwise they can lead to slowdowns or even complete shutdowns of your critical operations.
Managing a hybrid cloud environment can be quite intricate. It involves juggling multiple cloud providers, overseeing various data centres, and handling numerous applications, which can prove more challenging than it initially seems. This complexity often leads to difficulties in effectively monitoring and optimizing the setup, resulting in increased operational costs.
To address this complexity, consider implementing cloud management tools. These tools offer a unified view, acting as a single dashboard for monitoring and managing your hybrid cloud environment. With these tools, you can automate routine tasks like resource scaling and provisioning, ultimately reducing operational costs and enhancing overall efficiency.
When you're deploying multiple cloud platforms in a single environment, it becomes crucial to consider the pricing models tailored to each one and ensure your licensing and pricing choices align with your budget. Evaluate whether a fixed-price structure suits your needs better or if a consumption-based model is more cost-effective.
Failing to grasp these pricing models can result in receiving a substantial and unwelcome bill that catches you off guard. So, take the time to understand the pricing intricacies of each cloud platform and make informed decisions to keep your costs in check.
