The hybrid cloud: The best of on-premise and the cloud

When most people talk about cloud, they’re referring to a either a public or a private cloud offering, strategically positioning their assets in either one or the other. But there’s another way to utilise cloud services: Hybrid Cloud. This carries significant benefits for companies where access, security and data governance are key priorities.

What is the Brennan IT hybrid cloud?

Brennan IT’s hybrid cloud services combine on-site, client-owned hardware with Brennan IT’s private cloud services to allow customers to take advantage of the best aspects of cloud computing technology while remaining in control of their on-site hardware. This equipment can be self-managed or fully maintained through a Brennan IT managed service. High-use services that are required locally are deployed from your dedicated hardware on-site, to minimise network latency. Other services, like email, backups, SaaS, internet-facing workloads and test or development environments are deployed from a Brennan IT private cloud.

Who is it best suited for?

  • Businesses who want to take advantage of the cost-savings and scalability available to cloud users, without shifting their entire workload to the cloud.
  • Business who are concerned about the security and data governance with moving sensitive applications and data in the public cloud.
  • Businesses with multiple sites or heavily mobile workforces, where cloud enabling key applications provides security and flexibility.
  • Businesses with existing IT Assets that will continue to be leveraged over a number of years as a transition to cloud based services is achieved.
If you want to be more agile in terms of trialling and adopting new applications, have fluctuating IT needs, a desire for greater cost-savings, need financial transparency, or want to be able to scale easily with growth, a private cloud or a hybrid solution is a feasible option.

What are the advantages?

What makes the hybrid approach attractive to many businesses is the fact that it allows you to leverage your own assets as well as assets from a cloud service provider to create a more cost-effective and flexible IT environment. It gives you a way to augment your existing facilities, either in terms of handling bursts of traffic or having specific workloads hosted. With a hybrid cloud, you have full ownership of your own hardware, with the option to either maintain it yourself or out-task system maintenance to a service provider, giving you that added flexibility. Hybrid clouds also allow companies to free themselves of the need to run their own data centres. High-use and mission-critical applications and systems can be deployed from in-house hardware, and cloud services can be utilised for storage, mirrors, experimentation and low-use systems. Cloud storage is elastic – it can be expanded and contracted to meet your present storage needs, eliminating both up-front capital expenditure on storage hardware and the ongoing maintenance costs associated with a data centre. Most companies who run dedicated hardware without an integrated private cloud are paying for unused capacity on their in-house hardware, since running at full capacity on your own hardware can bring significant performance issues. Brennan IT’s hybrid cloud also means you won’t be paying for unused capacity on your dedicated hardware. You run your dedicated hardware at 100 per cent capacity, with spill over absorbed by the private cloud. Perhaps most importantly, the disaster recovery position of a company using Brennan IT’s hybrid cloud is significantly stronger than that of a company running only dedicated hardware, as they have the ability to store a comprehensive back-up of their crucial systems and data in the cloud. This means it can be recovered in the event of their dedicated hardware being irreparably damaged. To learn more about Brennan IT’s hybrid cloud service, contact your Brennan IT representative.
