What is a Private Cloud?

A private cloud is a computing environment available only to those within a given enterprise. It’s generally offered as infrastructure as a service (IaaS) or platform as a service (PaaS) with different advantages like self-service, scalability and customization. A private cloud may work on an internal network or through the Internet. Unlike public cloud, those utilizing private cloud are responsible for financing and maintaining the entire cloud infrastructure with internal IT staff.

Also known as “corporate” or “internal” cloud computing, a private cloud is open only to those with credentialed access. Unlike public cloud services, it does not share resources with any end-users outside of a given network. Dedicated to a single enterprise, this environment is ideal for storing proprietary information including financial data and medical records. Private clouds offer much of the same scalability of public clouds but lack the agility when they don’t run on the right architecture.

The pros and cons

A private cloud is built and deployed behind the enterprise firewall, and its upkeep and day-to-day maintenance falls under the purview of the internal company IT staff. The environments can vary greatly in size to meet the needs of everyone from sole proprietors to global corporate entities and government institutions. Working strictly within a proprietary network, it can offer better control of information. This does come at a greater cost in the human resources necessary for private cloud maintenance through an adept and highly knowledgeable staff of IT professionals.

The features you need

Because private cloud environments are incredibly dynamic, they’re also unpredictable. You need the storage that is consistent, autonomous and designed to do what it’s supposed to without a 24/7 IT babysitter. The conventional storage options available require manual configuration for a host of complicated instances that can cause latency events. What’s more, once you’ve configured traditional storage for pre-defined workloads, you’ll eventually have to reconfigure them all over again. This can be a tedious task and waste of resources.

To ensure best practices in private cloud storage performance, you need visibility across your entire infrastructure. You can stop end-to-end latency events when you can see exactly where the root of the issue is. A UI that shows all input/output (I/O) slowing and breakdowns right at the VM level offers the best storage performance in a dynamic environment.

Private cloud platform as a service (PaaS)

Platform as a service (PaaS) provides some great advantages for authentically private cloud computing services. It is a truly private cloud that offers self-service, simplification of software deployment and execution of other processes. PaaS offers a user interface (UI) that allows developers and IT professionals to access proprietary infrastructure quickly and easily. There’s no need for configuration. Applications are abstracted within a PaaS cloud, making for easier and quicker management of apps for everything from development to deployment and even production. When equipped with a user-friendly UI, the cost of running drops dramatically, as a sea of IT professionals are no longer needed for complex configuration. And, of course, PaaS is probably most loved for its great security from cyberattacks and data breaches. With zero shared assets there less ways for hackers to creep in.

Why infrastructure as a service (IaaS) isn’t a true private cloud offering

Every cloud computing service offers the ability to access storage and software in a virtualized environment. After all, any cloud is a virtual space. What IaaS changes is access to all information and apps on virtualized hardware. Examples of this could be virtual network connectivity, hosting, server space and data centers. However, IaaS offers these products and services as a third-party as well as all hardware, storage and components needed for an infrastructure to run correctly. IaaS are very popular because they offer greater agility and on-demand scalability that straightforward private clouds often lack.

IaaS providers offer automated policy and task execution and allow clients to pay for just what they use in a variety of methods. This includes monthly, weekly and even hourly. Some business owners see this “I only pay for what I use” approach as an advantage. Using this type of infrastructure, those at the enterprise level won’t have to underwrite the cost of housing hardware or software. However, IaaS cloud computing partners sometimes make clients pay for aspects of infrastructure they never used. This financial downside can mean spending money that could be better allocated to a truly private cloud environment.

Is there such a thing as a software as a service (SaaS) private cloud?

Many people confuse IaaS, PaaS and SaaS. The short answer to the question above is no. A private cloud can be the foundation for SaaS apps to run on, but the private cloud itself is not a type of software, virtual or otherwise. Third-party SaaS are offerings available through the Internet within private clouds, but the SaaS itself is not the cloud.

Welcome to Tintri Enterprise Cloud

The sluggishness often associated with private cloud is gone when you switch to Tintri Enterprise Cloud. That’s because Tintri uses the building blocks of cloud—VMs and containers—rather than their slower, less granular counterparts, LUNs and volumes. With this level of granularity, your venture can run multiple apps in multiple environments anywhere with zero latency.

Tintri Enterprise Cloud storage offers something else: analytics and automation

Unlike other types of private cloud options available for enterprise use, Tintri Analytics offers real-time storage and predictive analysis. Your team can measure and model the needs of your private cloud as they change. Putting game-changing analytics tools in the hands of your IT staff and developers allows them to review as many as 160,000 VMs in less than a second and apply what they’ve learned to create better capacity for overall enterprise growth or a specific one-off project. When you use Tintri Analytics, your private cloud environment becomes an automated space capable of adjusting as needed without any IT intervention.
