When it comes to the performance of clouds, several critical factors tilt the balance in favor of private cloud, especially for enterprises with specific demands.

1. Customization and Flexibility: Private cloud infrastructure can be customized to precisely match an organization’s unique performance requirements. This level of customization offers optimal configuration to run workloads most efficiently, thereby increasing overall system performance.
2. Dedicated Resources: With a private cloud, businesses get dedicated resources that are not shared with other users, as they would be in a public cloud environment. This guarantees availability and consistent performance, ensuring high-speed processing and minimal latency.
3. Data Gravity: The concept of data gravity – that large volumes of data are harder to move – means applications run more efficiently when they’re near the data. In a private cloud, data is stored and processed in the same location, minimizing time-consuming and expensive data transfers. This can give private clouds a performance edge, especially for data-heavy workloads.

So, while public clouds have their advantages, for organizations looking for optimal performance, customization, security, and data control, private clouds often provide a more suitable solution.

Legacy applications often run on outdated hardware and software infrastructure, which can limit their performance. Moving these applications to public cloud services without refactoring these apps normally ends in a degraded user experience and an explosion in cloud spend. Public Clouds just aren’t made for running legacy applications and this is where hybrid cloud solutions powered by Modern HPC provide far better outcomes in terms of user experience and costs.

Modern HPC enhances your legacy applications in several ways:

1. Improved Performance: HPC uses advanced computing resources to process data and perform operations at high speed. It can therefore execute tasks of legacy applications much faster than traditional computing environments, helping to improve the performance of these applications.
2. Parallel Processing: One of the primary features of HPC is its ability to perform parallel processing. This means that it can execute multiple tasks simultaneously, which is highly beneficial for applications with large and complex workloads. This can reduce the time it takes for these applications to process data or complete operations. Sometimes applications need some form of re-coding to optimally reap the benefits of HPC.
3. Efficient Use of Resources: HPC is more efficient in the use of hardware and software resources than traditional computing environments and public clouds. This leads to extensive cost savings.
4. Reliability and Availability: Modern HPC is designed with fault tolerance and high availability in mind, meaning they can continue to operate even when individual components fail. This is beneficial for legacy applications that need to be available around the clock.
5. Compatibility and Integration: Modern HPC runs on VMware for powering legacy workloads which makes it compatible with legacy applications, meaning they can be integrated without requiring significant changes to the application. Also, moving your applications from today’s VMware environments to Modern HPC only involves a simple lift and shift lowering the cost of migration significantly.

For businesses operating in highly regulated industries, maintaining security and compliance is crucial. A hybrid cloud allows sensitive data to be kept on a private cloud or on-premise, while other data and applications can take advantage of the cost savings of the public cloud.

Data sovereignty refers to the concept that digital data is subject to the laws of the country (or European Union) in which it is located or processed. For businesses with global operations, meeting data sovereignty requirements can be complex. Hybrid cloud solutions can help address this by giving businesses the flexibility to store and process data in specific locations that align with regulatory requirements.

Public cloud services can offer cost savings, but they can also be more expensive for certain types of workloads or data storage needs. A hybrid cloud approach allows businesses to optimize costs by balancing workloads between public and private resources.
