Private cloud, public cloud, hybrid cloud… When time comes to select a vendor, who’s been ramping up the charm for six months to sell you a B2B solution that pertains to the automation of your accounts receivable, it’s always a wise idea to ask him to open the hood. Thus, not only Finance but especially IT can get their hands dirty and quickly figure out, whether the irresistible charm displayed until the SOW landed on your desk does not hide serious issues, which you’d end up regretting fairly quickly. It’s all about making sure the vendor’s infrastructures are in line with the utmost advances in the industry, are irrefutably reliable, and can perform without the shade of a doubt.
Here at Amalto, we’re providing our customers with private clouds. What does that entail? A private cloud is similar to a public cloud in the sense that it offers comparable advantages such as scalability and self-service. The big differentiator is that a private cloud provides a proprietary architecture. In other words, a private cloud is solely dedicated to the needs and goals of one single organization (the client), whereas a public cloud delivers services to multiple organizations. A private cloud is a great fit for organizations that run their business in a highly dynamic or unpredictable environment (well, isn’t that the case for all operations after all?), which in turn necessitates the need to always change computing needs to retain or regain direct control over the environment: security, business governance, regulatory compliance requirements, among others.
3 Types of Clouds
There are three general cloud deployment models: public, private and hybrid.
- Public Cloud: It’s a cloud computing model, where a third-party provider makes compute resources available to the general public over the Internet. With public clouds, enterprises do not have to set up and maintain their own cloud servers in house. So, it’s a multi-tenant architecture with a pay-as-you-go pricing model. The top vendors are AWS, Microsoft Azure, Google Cloud Platform.
- Private Cloud: It’s a cloud computing model in which an enterprise uses a proprietary architecture and runs cloud servers within its own data center. Therefore, it’s a single-tenant architecture with on-premise hardware and direct control of the entire underlying cloud infrastructure. The top vendors are Dell EMC, IBM, Red Hat, Microsoft, HPE, VMware and OpenStack.
- Hybrid Cloud: It’s a cloud computing model that includes a mix of on-premises, private cloud and third-party public cloud services with orchestration between the two platforms. So, this model offers cloud bursting capabilities (love Kate Bush…) as well as the benefits of both public and private environments. The top vendors are a combination of both public and private cloud providers.
Private Cloud: 4 Main Advantages
In a nutshell, a private cloud shares the same advantages as a public cloud platform, with the additional capabilities that comes along with having total control over the resources of the physical hardware layer.
- Enhanced Security: Private clouds offer a level of security that public and even hybrid clouds cannot equal. Private clouds are much more secure because customers do not share any storage with other companies, which allows their infrastructure to be configured to their exact specifications. Private clouds are deployed inside the provider’s firewall and with dedicated intrusion prevention systems as well as customized networking, which ensures the continual optimization of performance. At Amalto, the physical machines are hosted at world-class data centers with anti-DDOS, electrical backup generators, fire prevention measures, physical access control, and temperature, humidity and pressure control. Access from the public Internet is granted via an API gateway which features OAuth2 secure authentication, secure reverse proxying and redundancy with automatic failover and anti-DDOS.
- Enhanced Control and Flexibility: Private clouds are built to meet the exact specifications of the organization it serves. Any requirement the buyer has can be translated into the way the private cloud is set up. A private cloud conforms to the (ever changing) performance, scaling, and architecture requirements of each customer. Moreover, with a private cloud, the customer has full-on control and transparency over who can access his data. The private cloud provider can indeed at any time let the customer know exactly where his data is being stored (unlike with public clouds) and ensure that only specific, authorized users have access to specified datasets.
- Enhanced Performance and Scalability: The resources of a private cloud are entirely at the disposal of the cloud’s owner, which instantly eliminates any risk of resource or capacity contention. Thus, at the virtual layer, scaling is a simple as deploying and configuring new cloud servers. At the physical layer, new servers can be quickly added to increase the overall capacity of the cloud platform.
- Enhanced Privacy and Compliance: Public cloud platforms are multi-tenant infrastructure products, which can make them unsuitable for some applications. So, when a business needs its cloud platform to comply with a regulatory framework, then a serious problem arises. The fact that a private cloud means that the physical infrastructure is private to the customer facilitates sudden changes in compliance.
