Cloud Community - GreenView Enterprise Cloud Services

Cloud Computing refers to a recent trend in Information Technology (IT) that moves computing and data away from desktop and portable PCs into large data centers. The key driving forces behind the emergence of Cloud Computing includes the overcapacity of today's large corporate data centers, the ubiquity of broadband and wireless networking, the failing cost of storage, and progressive improvements in internet computing software. Currently, the main technical underpinnings of Cloud Computing infrastructure and services include virtualization, service-oriented software, grid computing technologies, management of large facilities, power efficiency, etc.
The emergence of Cloud Computing promises to streamline the on-demand provision of software, hardware, and data as a service, achieving economies of scale in the deployment and operation of IT solutions. It is believed that Cloud Computing will be a disruptive technology with profound implications not only for internet services but also for the IT sector as a whole.




Introduction
GreenView provides Cloud Computing infrastructure and services to all industries. We make it possible to our clients to quickly move from an idea to a web application with millions of users - without the pain of large capital outlays and long-term vendor contracts. GreenView provides all this flexibility and also delivers all the security, cost stability, and enterprise-grade performance of a dedicated private data center.

Flexibility
GreenView infrastructure is designed to let you dynamically add more servers very quickly. We regularly help clients go from one user to an infrastructure capable of supporting several million total users. The whole process takes only a couple of hours.

No Contracts: Month to Month Pricing Delivers the Ultimate Flexibility
Pay for only what you use. You can scale up or scale down as you need to. You can also pay annually if you prefer, and get one month free.

GreenView's Cloud is Entirely Open
Direct Compatibility with Legacy Software: GreenView's cloud is built on VMWare infrastructure. Your application can be running on OS requested.
No Application rewrites required: CIOs don't want to have to rewrite apps when they move to the cloud. Google app engine, for example, requires that you completely rewrite large sections of your code.

Open means less risk - you can leave: CIOs often tell us that they like to know that they can leave GreenView if they want to. If you don't have to rewrite your app to move into GreenView, you don't have to rewrite your app to move off. One major advantage of our approach is that it reduces the risk of adopting a cloud solution.

Lower Total Cost of Ownership
On GreenView, you do not have to build new tools just to manage your application in the cloud.
CIOs are concerned about operational management overall and yet whole company have to deal with the complexity of running ethereal virtualized server. These extra operational hurdles simply do not exist at GreenView. Our approach to virtualization requires much lower administrative overhead. Cloud computing promises flexibility, but it shouldn't force enterprise users into an expensive tradeoff where they have to deal with additional operational costs simply to gain that flexibility.

RTO & RPO

Before you decide the Business Continuity model, you must understand RTO & RPO to address your company business requirment.

RTO (recovery time objective) is the time that elapses between the loss of access to data and the recovery of data access. The shorter the RTO, the better. RPO (recovery point objective) is the point in time when the data backup took place. In a mission-critical environment such as a real-time order processing system, an acceptable RPO may be one hour after the failure. In a less-critical computer application such as a seldom-accessed storage repository, an RPO of one week after the failure may be acceptable. It is up to you as a security consultant to help your client determine an appropriate RTO and RPO and provide the products and services to meet those objectives.
Our BCServices deliverable suitable RTO and RPO to make your business competitveness in the information avalibility. you can define RTO and RPO below than 2 hour beetwen tier 6 - 7 in the chart below.

The Seven Tiers was defined to help identify the various methods of recovering mission-critical computer systems as required to support business continuity.Business Continuity Planning (BCP) and Disaster Recovery Specialists today continue to use the 7-Tier concept as it is very useful in illustrating continuity capabilities and at a high level, their associated costs. The definitions for the various Tiers have been updated as technology has evolved in support of today's business requirements and their associated Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO). The seven tiers of business continuity solutions offer a simple method to define your current service levels, risks and where you really want or need to be.
Tier 0: No off-site dataBusinesses with a Tier 0 business continuity solution have no Business Continuity Plan. There is no saved information, no documentation, no backup hardware, and no contingency plan. The time necessary to recover in this instance is unpredictable. In fact, it may not be possible to recover at all.
Tier 1:

Data backup with no hot siteBusinesses that use Tier 1 continuity solutions back up their data and send these backups to an off-site storage facility. The method of transporting these backups is often referred to as "PTAM" - the "Pick-up Truck Access Method." Depending on how often backups are created and shipped, these organizations must be prepared to accept several days to weeks of data loss, but their backups are secure off-site. However, this tier lacks the systems on which to restore data.
Tier 2:

Data backup with a hot siteBusinesses using Tier 2 business continuity solutions make regular backups on tape. This is combined with an off-site facility and infrastructure (known as a hot site) in which to restore systems from those tapes in the event of a disaster. This solution will still result in the need to recreate several hours or even days worth of data, but the recovery time is more predictable.
Tier 3:

Electronic vaultingTier 3 solutions build on the components of Tier 2. Additionally, some mission critical data is electronically vaulted. This electronically vaulted data is typically more current than that which is shipped via PTAM. As a result there is less data recreation or loss after a disaster occurs.
The facilities for providing Electronic Remote Vaulting consists of high-speed communication circuits, some form of channel extension equipment and either physical or virtual Tape devices and an automated tape library at the remote site.
Tier 4:

Point-in-time copiesTier 4 solutions are used by businesses that require both greater data currency and faster recovery than users of lower tiers. Rather than relying largely on shipping tape, as is common on the lower tiers, Tier 4 solutions begin to incorporate more disk based solutions. Several hours of data loss is still possible, but it is easier to make such point-in-time (PiT) copies with greater frequency than tape backups even when electronically vaulted.
Tier 5:

Transaction integrityTier 5 solutions are used by businesses with a requirement for consistency of data between the production and recovery data centers. There is little to no data loss in such solutions, however, the presence of this functionality is entirely dependent on the application in use.
Tier 6:

Zero or near-Zero data lossTier 6 business continuity solutions maintain the highest levels of data currency. They are used by businesses with little or no tolerance for data loss and who need to restore data to applications rapidly. These solutions have no dependence on the applications or applications staffs to provide data consistency.Tier 6 solutions require some form of Disk Mirroring. There are various synchronous and asynchronous solutions available from the mainframe storage vendors. Each solution is somewhat different, offering different capabilities and providing different Recovery Point and Recovery Time objectives. Often some form of automated tape solution is also required. However, this can vary somewhat depending on the amount and type of data residing on tape.
Tier 7:

Highly automated, business integrated solutionTier 7 solutions include all the major components being used for a Tier 6 solution with the additional integration of automation. This allows a Tier 7 solution to ensure consistency of data above that which is granted by Tier 6 solutions. Additionally, recovery of the applications is automated, allowing for restoration of systems and applications much faster and more reliably than would be possible through manual business continuity procedures.
Recovery Objectives The Recovery Time Objective (RTO) and Recovery Point Objective (RPO) along with cost are important criteria when evaluating the right solutions.
Recovery Time Objective:
The Recovery Time Objective (RTO) describes the time within which business functions or applications must be restored (includes time before disaster declared and time to perform tasks).
Recovery Point Objective:
The Recovery Point Objective (RPO) describes the point in time to which data must be restored to successfully resume processing (often thought of as time between last backup and when outage occurred). Many solutions are available. Choosing the right ones requires that you balance the cost of the solution against the costs associated with downtime and lost data. Some amount of data loss may be acceptable if the data can be captured from other sources or easily recreated.

This is not a one-size fits all solution. The very best practice for any organization is to implement an appropriate blending of these tiers. In this way, you can implement the correct level of Disaster Recovery protection at the lowest possible cost. A single solution or technology isn't usually the best choice for all applications.

What is Business Continuity?

Today's senior management, with ever increasing time to market and resource constraint pressures, will need the answers to two major questions when considering the value of any proposed investment in improving business continuity IT Infrastructure. These questions are:

What is the overall value proposition of Business Continuity to the business itself and what functions of Business Continuity do for our daily competitiveness, responsiveness, expense posture, and profit?

What is the relationship between these business benefits and associated IT Infrastructure and IT operations requirements?

The Answer is:
The ability to adapt and respond to risks, as well as opportunities, in order to maintain continuous business operations, be more trusted partner, and enable growth.

What is Green Data Center?

Issues and opportunities around energy, the environment, and sustainability impact every individual and every business, worldwide. Energy usage is becoming the largest single data center operating cost — at 30-40% of the operational budget today. Within the next few years, it is estimated the cost to power a server will equal the acquistion cost of the server. These critical energy and power costs should be solve through an optimized IT infrastructure. By combining hardware, software and services offerings, we can meet all of our business goals — performance, availability, simplicity — while addressing energy and cooling concerns.

Green Data Center means simplify, less power, and manageable system that can bring business continuity and save the world from critical energy resources.
