The Vision for Private Cloudby QArea Expert on June 16, 2011
Private cloud computing presents a model of shifting from customized to standardized system. Within such an environment the management is no longer about keeping off change but in return embracing it to make easier IT’s twin goals by means of delivering on the business needs and handling the primary resources in possible the most effective way.
The primary to reaching greater operational efficiency is standardization. Private clouds do not just make standardization easy but noticeably extends the returns on standardization. Employing standard infrastructure from a catalogue of applications makes orders of magnitude easier and faster than creating every application form scratch. The same gains are available from standardizing and centralizing high availability, security and network management.
Management, in the cloud computing, will develop from minimizing and preventing change to covering constant change such as the natural state of IT. For instance, moving of an app from one server to another, in the physical world, means both risk and down-time and requires careful tracking and planning in a Change Management Database (CMDB). For comparison, in a cloud environment alteration at any level is included and accomplished automatically grounded on predefined policies. VMware vMotion is riskless, automated and fast, yielding serious efficiency and utility improvements.
The quickness of a private cloud infrastructure allows you to offer every application the resources it requires now, adapting as demand changes. Management is focused on 2 clear needs: assuring that every application satisfies the business needs (performance, security, availability) and rendering the pool of resources to fill the aggregate needs of the company in the most effective and reciprocal way possible.
Core differences in approach of Management:
- Change is thoroughly planned, manual, slow and risky
- Static bindings between applications, infrastructure and processes
- Management software performs to the lowest common dnominator
- Heterogeneous processes and elements across silos
Private Cloud Management
- High-level abstraction and massive standardization
- Dynamic relationships all over layers of the technology stack
- Day-to-day is automated; tools of management should focus on higher order tasks
- Change is automated and constant
In order to derive benefit of the cloud, there requires being a clear separation of the consumption versus production layer. Within the cloud, the user (the business) has no idea and essentially, few interest in or concern with – which management tools and hardware platform are being deployed to implement services.
Traditional approaches for defending the applications and operating system have relied solely on agents, who are vulnerable by themselves, offer protection just with limited layers of the application + OS stack, and build sprawl and update management issues on a large scale. The VMware vSphere platform possesses unique introspection abilities and delivers effective and comprehensive access to security controls at the time of obviating the necessity for security agents in every virtual machine, recognizing hard-to-detect problems efficiently and precisely.
