Managed Private Cloud Stacks Trying To Find Their Way In The Enterprise
In this way, a private cloud can make it easier for an organization to customize its resources to meet specific IT requirements. Private clouds are often used by government agencies, financial institutions, any other mid- to large-size organizations with business-critical operations seeking enhanced control over their environment.
Managed private cloud stacks trying to find their way in the enterprise
Today, anyone who uses a or mobile phone almost certainly uses some form of SaaS. Email, social media, and cloud file storage solutions (such as Dropbox or Box) are examples of SaaS applications people use every day in their personal lives. Popular business or enterprise SaaS solutions include Salesforce (customer relationship management software), HubSpot (marketing software), Trello (workflow management), Slack (collaboration and messaging), and Canva (graphics). Many applications designed originally for the desktop (e.g., Adobe Creative Suite) are now available as SaaS (e.g., Adobe Creative Cloud).
VMware is a global leader in cloud infrastructure, and VMware Private Cloud offers a service enabling organizations to simply pool all their servers into a single resource, which can be distributed among virtual machines (VMs) that run application workloads across the enterprise.
A hosted private cloud is hosted by the cloud provider and can reside on-premises or in a data center. These resources are not shared with other organizations and are managed by the cloud service provider. All updates, upgrades, and maintenance are the responsibility of the cloud provider.
A managed private cloud offloads many responsibilities of cloud management to a third party hosting partner. Hardware, software, networking, and operations of the private cloud are handled by the provider, who may offer other value-added services such as backup and business continuity.
With private clouds, you're completely responsible for all costs at all times. You staff, manage, and maintain all underlying infrastructure. But private clouds can also be delivered by cloud providers as part of a managed private cloud approach.
Managed private clouds let customers create and use a private cloud that's deployed, configured, and managed by a third-party vendor. It's a cloud delivery option that helps enterprises with understaffed or underskilled IT teams provide better private cloud services and infrastructure to users without the day-to-day complexities of managing a private cloud themselves.
The best way to consume Elastic is Elastic Cloud, a public cloud managed service available on major cloud providers. Customers who want to manage the software themselves, whether on public, private, or hybrid cloud, can download the Elastic Stack.
Predefined, validated, and tested cloud modules that are production-ready and workload-optimized to deliver consistent performance for your apps. Users can self-serve VMs, containers or bare metal using an intuitive portal, APIs, CLIs, or infrastructure as code (IaC), giving developers immediate access to their workspace with the flexibility to choose from a variety of OS / containerized app stacks, and seamless toolchain integration.
A private cloud is a single-tenant computing infrastructure and environment, meaning the organization using it -- the tenant -- doesn't share resources with other users. Private cloud resources can be hosted and managed by the organization in a variety of ways. The private cloud might be based on resources and infrastructure already present in an organization's on-premises data center. Conversely, a private cloud may be implemented on new or separate infrastructure, which is provided by the organization or a third-party organization. In some cases, the single-tenant environment is enabled by solely using virtualization software. In any case, the private cloud and its resources are dedicated to a single user or tenant.
Private clouds are often deployed when public clouds are deemed inappropriate or inadequate for the needs of a business. For example, a public cloud might not provide the level of service availability or uptime that an organization needs. In other cases, the risk of hosting a mission-critical workload in the public cloud might exceed an organization's risk tolerance, or there might be security or regulatory compliance concerns related to the use of a multi-tenant environment. In these cases, an enterprise might opt to invest in a private cloud to realize the benefits of cloud computing while maintaining total control and ownership of its environment.
The main advantage of a private cloud is that users don't share resources. Because of its proprietary nature, a private cloud computing model is best for businesses with dynamic or unpredictable computing needs that require direct control over their environments, typically to meet security, business governance or regulatory compliance requirements.
Private clouds also have some disadvantages. First, private cloud technologies -- such as increased automation and user self-service -- can bring considerable complexity to enterprise IT. These technologies typically require an IT team to rearchitect some of its data center infrastructure as well as adopt additional software layers and management tools. As a result, an organization might have to adjust or even increase its IT staff to successfully implement and maintain a private cloud. Private clouds can also be expensive; often, when a business owns its private cloud, it bears all the acquisition, deployment, support and maintenance costs involved.
Hosted private clouds, while not outright owned by the user, can also be costly. The service provider takes care of basic network maintenance and configuration in a hosted deployment, which means the user needs to subscribe and pay regularly for that offered service. This can end up being more expensive than the upfront cost of complete ownership in the long run and sacrifices some of the control over maintenance that complete ownership guarantees. Although users will still be operating in a single-tenant environment, providers are likely serving multiple clients and promising them each a catered, custom environment. If an incident occurs on the provider's end -- an improperly maintained or overburdened server, for example -- users may find themselves facing the same problems the public cloud presents: unreliability and lack of control.
The above list categorizes different types of private clouds by the way they're hosted and to what extent they're managed by the provider. Infrastructure is also a way to categorize different types of private clouds, such as the following:
As mentioned, operating a private cloud on premises is generally more expensive upfront than using a public cloud for computing as a utility. This is due to back-end maintenance expenses that come with owning a private infrastructure and the capital expense of implementing one. However, a managed private cloud can mitigate those costs and, in some cases, even be cheaper than a standard public cloud implementation.
Vendors offer a few different pricing models for managed private clouds. The pricing model and price itself can vary depending on the private cloud hardware and software offered and the level of management provided by the vendor. Often the pricing is based on packages of hardware, software and services that can be used in private cloud deployments. For example, VMware prices its virtualization platform vSphere using a yearly subscription and support model, with one yearly price for a basic subscription or a slightly higher price for a production-level subscription and a flat license fee.
Understanding pricing models for managed private cloud deployments can get complicated. Many vendor websites don't offer a straight-ahead private cloud package. Instead, they sell a spectrum of different hardware, software and services that a company can use to deploy a private cloud. Often, the pricing for these products isn't made explicitly clear on vendor websites, and buyers are prompted to speak with a salesperson once they've reached the part of the website that focuses on purchase intent. This is likely because private clouds -- and managed clouds, especially -- need to be specifically tailored to an organization's needs. Buyers should understand which business processes specifically require the cloud and why they need flexible and scalable cloud infrastructure so that they can make an informed choice with the vendor on the proper cloud deployment and the products that form it most efficiently.

It can also be deployed in your public cloud environment with Tanzu Mission Control to enable development teams to quickly spin up managed Kubernetes clusters in their public cloud accounts, while maintaining access to the control plane for security and customization.
Business policy needs, such as having to run your workloads at specific geographical locations, may make it difficult to use public clouds. Additionally, some enterprises may not be able to utilize public cloud offerings from a specific cloud provider due to their business policies related to competition.
Many enterprises may not wish to be tied to a single cloud provider and hence may want to deploy their applications across multiple clouds, including an on-premises private cloud. This could potentially reduce business continuity risk due to issues with a specific cloud provider. It also gives you leverage around price negotiation with your cloud providers.
