Infrastructure as a Service

Private Cloud

Private cloud is a type of cloud computing that delivers similar advantages to public cloud, including scalability and self-service, but through a proprietary architecture. Unlike public clouds, which deliver services to multiple organizations, a private cloud is dedicated to a single organization.

As with other cloud models, private clouds will provide computing power as a service within a virtualised environment using an underlying pool of physical computing resource. However, under the private cloud model, the cloud (the pool of resource) is only accessible by a single organisation, therefore providing that organisation with greater control and privacy.

Private clodu benefits:

  • HIGH AVAILABILITY - virtualization software takes care of availability in the event of a part of the system failure
  • SECURITY - greater level of control over data by implementing various security protocols (encryption, tunneling, private IP)
  • SCALABILITY - a higher level of scalability using public cloud infrastructure resources

Hybrid Cloud

Hybrid Cloud

Hybrid cloud is a solution which uses a combination of private and public cloud.
It is suitable for companies who want to keep a critical part of the infrastructure inside private cloud, while other less critical parts, such as a test environment, can be kept in the public cloud. Hybrid cloud gives companies greater flexibility and more data deployment options.

A good example for the use of hybrid cloud are dynamic environments where the system load is very variable (processing systems that experience an increased load in certain time of the day or season). The system can be installed in a private environment, and can use the added resources from the public cloud at increased load time.

The hybrid cloud has its application in Big Data processing. The client can use a private cloud to store sales data, orders, etc., while the public cloud is used for analytics and can be scaled in case of additional resources are needed when processing analytics.

In any case, the flexibility and scalability of the public cloud eliminate large infrastructure investments in the event of a short-term need to increase resources.

Storage as a Service

Storage as a service is a service where companies can lease or rent storage infrastructure. Small companies and individuals often find this to be a convenient methodology for managing backups, and providing cost savings in personnel, hardware and physical space.

Storage as a Service is generally seen as a good alternative for a small or mid-sized business that lacks the capital budget and/or technical personnel to implement and maintain their own storage infrastructure. SaaS is also a way for all businesses to mitigate risks in disaster recovery, provide long-term retention for records and enhance both business continuity and availability.

The key advantage to SaaS is in cost savings -- in personnel, in hardware and in physical storage space. For instance, instead of maintaining a large tape library and arranging to vault (store) tapes offsite, a network administrator that used SaaS for backups could specify what data on the network should be backed up and how often it should be backed up.

Backup as a Service

Backup as a Service

Backup as a service is a service of backing up data that involves purchasing backup and recovery services from an online data backup provider. Instead of performing backup with a centralized, on-premises IT department, BaaS connects systems to a private, public or hybrid cloud managed by the outside provider. Backup as a service is easier to manage than other offsite services. Instead of worrying about rotating and managing tapes or hard disks at an offsite location, data storage administrators can offload maintenance and management to the provider.

BaaS may be used when an organization has outgrown its legacy storage backup and would have to go through a costly upgrade, or lacks the resources for on-premises, high-level backup. Outsourcing backup and recovery to a provider can also keep data accessible or restorable from a remote location in case of an outage or failure.
