The term “private cloud” is often taken to imply single-tenancy — one set of hardware, configured and operated to meet the needs of one organization. This is contrasted to the public cloud — a massively multi-tenant cloud on a large, shared pool of resources.
This perception contributes to the belief that the private cloud is on the way out. After all, cost cutting is still one of the main benefits of moving to the cloud, and dedicated hardware is costly.
But this division is too simplistic. Even a private cloud hosting a single organization is multi-tenant in a sense — there can be dozens of departments, applications and environments, and thousands of users. The benefits of private cloud managed services don’t go away just because the cloud has many separate pieces — or separate organizations.
In the multi-tenant private cloud, each organization has its own tailor-made environment within a larger resource pool, protected by a combination of logical and physical controls configured by a managed services provider. This gives tenants the benefits of private cloud managed services, combined with the best features of the public cloud.
Benefits of Private Cloud Managed Services
While public clouds typically offer architecture in standardized units, a managed private cloud is tailored to meet the tenant’s needs — a crucial feature for applications like SAP HANA that are sensitive to architecture. This customization also supports enhanced security and compliance needs like PCI DSS, which are difficult to meet in a public cloud.
Stability and performance are major benefits of private cloud computing. Public clouds pack tenants into white label hardware, resulting in inconsistent performance — i.e., noisy neighbors — and inadequate hardware reliability. Private managed clouds are provisioned carefully on high-quality hardware, with extra compute to cope with demand surges. The MSP monitors hardware for early warning signs and services it before it breaks down. This provides the consistency and ultra-low downtime mission critical applications require.
But for many organizations, the biggest benefit of private cloud computing is peace of mind. Instead of floating somewhere in a vast public cloud, your mission-critical applications are carefully supervised in a purpose-built data center, by an MSP who knows your system inside and out.
Benefits of Private Cloud Multi-tenancy
Multi-tenant private clouds share the cost benefits of public cloud computing. In fact, for performance-sensitive workloads, the private cloud is often the less costly option. The MSP can size the landscape more precisely, and the tenant doesn’t need to reserve surplus compute to deal with unpredictable performance degradation.
Multi-tenancy also supports rapid scaling — not traditionally a private cloud benefit. Like in the public cloud, customers only pay for what they use, and can provision extra compute as needed. In some cases, private cloud MSPs can provide better scaling by breaking virtualization limits the tenant would face in a public cloud.
The Benefits of Private Cloud Managed Services Will Continue to Grow
A managed, multi-tenant environment combines the security, stability and configurability benefits of private cloud hosting with the affordability and scalability of the public cloud. Public cloud hosting has its place, but for demanding, complex and mission-critical workloads, private cloud adoption will continue to grow.
