More and more businesses are embracing cloud services and reducing their reliance on in-house data centers. The benefits of cloud services like cost savings, flexibility, and scalability are compelling. However, data centers still have an important role to play for many organizations. The key is finding the right balance between cloud and on-premises infrastructure. In this blog post, we’ll examine the pros and cons of each approach and provide guidance on how to successfully adopt a hybrid model.
The Rise of Cloud Services
There’s no denying the momentum behind cloud adoption. According to Gartner, the worldwide public cloud services market is forecast to grow 17% in 2022 to reach $494.7 billion. Cloud services provide a pay-as-you-go model that eliminates big upfront investments in hardware and data centers. Businesses only pay for the resources they use each month. Cloud also provides instant scalability to support growth and seasonal peak demand. If more capacity is needed, it can be spun up immediately.
The major public cloud providers like AWS, Microsoft Azure, and Google Cloud Platform operate data centers around the world. This gives customers geographic coverage and redundancy to ensure application availability. The hyperscale cloud platforms also offer ready-made services like AI, big data analytics, cybersecurity tools and more. Businesses can leverage these advanced technologies without having to build them from scratch.
The Case for On-Premises Data Centers
With all the hype around the cloud, it may seem that the days of on-premises data centers are numbered. However, they still play a critical role for many organizations today and will continue to do so in the future. Data centers provide dedicated resources, security, control, and performance optimizations that public clouds may lack.
Data sovereignty is a key driver for maintaining on-premises infrastructure. Highly regulated industries like healthcare and financial services often must keep data within specific geographic boundaries. Businesses also keep sensitive data like intellectual property and trade secrets on-premises to minimize security risks. Compliance with regulations like GDPR is easier when data stays local.
Legacy applications that would require refactoring to run in the cloud are often kept in data centers. Performance-intensive workloads like data analytics, ERP systems, and transactional databases also benefit from being on dedicated infrastructure. Network latency and variability can degrade performance in the public cloud. Data centers within close proximity to users and other company facilities provide reliable connectivity.
The Hybrid Approach
Rather than taking an all-or-nothing approach, many organizations are opting for a hybrid model. Determining what goes where is a careful balancing act based on application characteristics, security requirements, and cost. Here are some best practices that can help strike the right balance:
– Keep highly sensitive, regulated workloads on-premises and everything else in the cloud. This isolates the most critical data while taking advantage of cloud efficiencies.
– Modernize older apps and move them to the cloud where possible. Prioritize based on cost/effort analysis.
– Use cloud for development, testing, disaster recovery, and bursting capacity. This takes advantage of cloud agility and availability.
– Connect cloud and data centers with high-speed, low-latency networking like ExpressRoute. This reduces data transfer costs and lag.
– Containerize applications to improve portability between environments. Kubernetes simplifies orchestration.
– Implement consistent security, governance, and DevOps patterns across cloud and data centers. This creates operational efficiency.
– Leverage cloud-based data services like data lakes and analytics. This provides flexibility while keeping primary data on-premises.
– Use cloud monitoring and management tools to maintain visibility across environments.
The hybrid model allows organizations to be strategic. With workloads placed optimally based on business needs, companies can innovate faster while also keeping their most critical assets secure and performing well.
Finding the Right Balance for Your Business
As you consider migrating to the cloud, don’t just lift and shift all data centers blindly. Conduct assessments of application portfolios, security requirements, networking topology and end user locations. This analysis will reveal which workloads truly require on-premises infrastructure versus those that can fully benefit from public cloud services.
Focus first on the low hanging fruit – development, testing, DR and backup use cases that naturally lend themselves to the public cloud. For more complex mission-critical systems, take a phased, proof-of-concept approach. This allows time for modernizing, containerizing and performance testing application before full production rollout.
Work closely with cloud and infrastructure architects to design optimal hybrid environments. The goal is to find the right balance between flexibility, security and performance at the lowest cost. A hybrid model done right can provide the best of both worlds.
