Previously thought of as a jumping off point for a true private or public cloud, the hybrid cloud model is proving itself as the final destination for enterprise IT.
A hybrid cloud allows enterprises to retain control of their IT environments while sending non-mission-critical workloads to the public cloud to take advantage of flexibility and scalability.
Though a hybrid cloud is built by combining at least one public and private cloud, deployment isn't that simple. Creating a hybrid cloud is complex work, as companies face problems with integration, migration and other hassles.
Still, the cloud provider market is listening. Vendors such as Red Hat, Amazon Web Services and VMware have introduced their own hybrid cloud services, and third-party organizations are creating tools to manage and deploy hybrid clouds.
Though the hybrid cloud model capitalizes on the benefits of both public and private clouds, it's not without its own risks. Debates about cloud security still linger, and the approach doesn't free you from unfair or confusing service-level agreements. But hybrid cloud can also solve many cloud risks by introducing cloud bursting and disaster recovery in what may be a more effective manner.
This essential guide hits on all the hybrid cloud model hot points -- deployment, management, the debates and the risks -- to ensure you're up to date on what could be the cloud model of the future.
1Hybrid cloud deployment-
Beginning a hybrid cloud project
The hybrid cloud model consists of at least one public cloud and one private cloud -- but deploying one isn't as easy as 1+1. Getting a hybrid cloud project off the ground means dealing with migration and integration challenges. Understanding how to get started on your hybrid cloud will be the key to success -- from choosing a provider to planning and executing a migration.
Moving from public cloud to a hybrid cloud environment means choosing among cloud stacks, such as OpenStack, Citrix CloudStack or Eucalyptus. Choose wisely; a do-over will cost you. Continue Reading
Although industry projections show enterprises will review or adopt hybrid cloud computing this year, many companies remain unclear on the basics. By simply following the NIST definition of hybrid cloud, enterprises may be missing three key pieces: security, connectivity and portability. Continue Reading
As cloud analysts foretell a strong year for hybrid cloud, enterprises look to make it a reality in production environments. Continue Reading
PaaS and SaaS can create more application integration problems than either IaaS or on-premises IT, but hybrid clouds may be able to help. Continue Reading
Using Agile and DevOps practices can make it easier to manage enterprise application deployment in a hybrid cloud, but achieving this kind of strategy takes careful planning. Continue Reading
2Hybrid cloud management-
Fine-tuning management strategies for the hybrid cloud
Once your hybrid cloud project is off the ground, you have to keep it up and running. You don't have to reinvent the wheel; management strategies for public and private clouds can be adjusted for your new IT environment -- but even that can be difficult. Make use of tools and tricks to effectively manage your hybrid cloud.
Hybrid cloud management is tricky, and though cloud management tools have emerged, many lack the capabilities of traditional management stacks that enterprise IT has come to rely on. Continue Reading
3Hybrid cloud architecture-
Where hybrid cloud fits in the public vs. private cloud debate
By now, it's clear to enterprises and SMBs alike that public cloud can offer scalability, flexibility and other benefits, while private cloud capitalizes on increased control and, debatably, security. But companies don't have to choose sides in the public cloud versus private cloud battle. With hybrid cloud, enterprises can choose to have the best of both cloud worlds. Despite the past, the hybrid cloud model is rapidly becoming a destination architecture for IT departments, not just a stop along the way. And cloud providers are listening and pushing hybrid cloud services onto the market.
The hybrid cloud model, BMC CTO Kia Behnia argues, is more than a stepping stone for enterprises migrating to cloud; it's the final goal. Continue Reading
IT pros need to piece together the best public and private components for a hybrid cloud deployment, considering factors such as security, interoperability and management. Continue Reading
VMware's new vCloud Hybrid Service hopes to draw its faithful users to its own public cloud services, after years of pushing enterprises to its vCloud Powered Services partners. Continue Reading
A hybrid cloud model offers the best of public and private clouds. But a hybrid cloud's success begins with the integration method you choose to build it. Continue Reading

Public cloud applications are similar to private cloud apps, but there are a few key differences that experts warn could case issues if unacknowledged. Continue Reading
4The hybrid cloud debate-
Assessing the risks of the hybrid cloud model
Though the hybrid cloud model seems to be a perfect solution for an enterprise IT department that wants control, security and all of the benefits of cloud services, a hybrid approach isn't without its own risks. Security remains an obstacle for IT departments -- when those IT departments can agree on a hybrid cloud vision in the first place. However, apps like cloud bursting and tools for management and identity can help smooth over some of these lingering debates on the validity of the hybrid cloud model in production environments.
