Types of Cloud Services.

There are many iterations that companies look to in order to actually use the technology. Cloud computing offers a variety of ways for businesses to increase their IT capacity or functionality without having to add infrastructure, personnel, and software.

Here are SIX different types of cloud computing and a little bit about what they offer to businesses:

1. Web-based cloud services. These services let you exploit certain web service functionality, rather than using fully developed applications. For example, it might include an API for Google Maps, or for a service such as one involving payroll or credit card processing.

2. SaaS (Software as a Service). This is the idea of providing a given application to multiple tenants, typically using the browser. SaaS solutions are common in sales, HR, and ERP.

3. Platform as a Service. This is a variant of SaaS. You run your own applications but you do it on the cloud provider’s infrastructure.

4. Utility cloud services. These are virtual storage and server options that organizations can access on demand, even allowing the creation of a virtual data center.

5. Managed services. This is perhaps the oldest iteration of cloud solutions. In this scenario, a cloud provider utilizes an application rather than end-users. So, for example, this might include anti-spam services, or even application monitoring services.

6. Service commerce. These types of cloud solutions are a mix of SaaS and managed services. They provide a hub of services which the end-user interacts with. Common implmentations include expense tracking, travel ordering, or even virtual assistant services.

These are, of course, just the beginning. There are constantly new ideas and new iterations being brought to the forefront. As cloud computing becomes a viable and even necessary option for many businesses, the types of services that providers can offer to organizations will continue to grow and grow.

Basic Cloud Type

Cloud computing comes in three forms based services: 

public clouds

private clouds

 hybrids clouds

Depending on the type of data you're working with, you'll want to compare public, private, and hybrid clouds in terms of the different levels of security and management required.

Public Clouds

A public cloud is basically the internet. Service providers use the internet to make resources, such as applications and storage, available to the general public, or on a ‘public cloud.  Examples of public clouds include Amazon Elastic Compute Cloud (EC2), IBM’s Blue Cloud, Sun Cloud, Google AppEngine and Windows Azure Services Platform.

For users, these types of clouds will provide the best economies of scale, are inexpensive to set-up because hardware, application and bandwidth costs are covered by the provider.  It’s a pay-per-usage model and the only costs incurred are based on the capacity that is used.

There are some limitations, however; the public cloud may not be the right fit for every organization. The model can limit configuration, security, and SLA specificity, making it less-than-ideal for services using sensitive data that is subject to compliancy regulations.

Private Clouds

Private clouds are data center architectures owned by a single company that provides flexibility, scalability, provisioning, automation and monitoring.  The goal of a private cloud is not sell “as-a-service” offerings to external customers but instead to gain the benefits of cloud architecture without giving up the control of maintaining your own data center.

Private clouds can be expensive with typically modest economies of scale. This is usually not an option for the average Small-to-Medium sized business and is most typically put to use by large enterprises. Private clouds are driven by concerns around security and compliance, and keeping assets within the firewall.

Hybrid Clouds

By using a Hybrid approach, companies can maintain control of an internally managed private cloud while relying on the public cloud as needed.  For instance during peak periods individual applications, or portions of applications can be migrated to the Public Cloud.  This will also be beneficial during predictable outages: hurricane warnings, scheduled maintenance windows, rolling brown/blackouts.

The ability to maintain an off-premise disaster recovery site for most organizations is impossible due to cost. While there are lower cost solutions and alternatives the lower down the spectrum an organization gets, the capability to recover data quickly reduces. Cloud based Disaster Recovery (DR)/Business Continuity (BC) services allow organizations to contract failover out to a Managed Services Provider that maintains multi-tenant infrastructure for DR/BC, and specializes in getting business back online quickly.

What is Cloud Computing

Cloud Computing is one type of computing technology where client connect the server through application that run on personal computer and other devices like smart phones tablets etc. You may think this is what traditional client-server model do. But the difference is rather than connecting the local database you are going to access Cloud Database that is similar to a centralized database then the computing process may run on one or more computer at the same time to utilizing the resource or data in the cloud database.

 So they use the concept of virtualization that is one or more physical servers can be partitioned and configured into multiple independent that is single server as many servers like disk partition all functioning independently and appearing to the user to be a single physical device. Such virtual servers do not physically exist and can therefore be moved around and scaled up or down on the fly without affecting the end user. 

The computing resources have become "granular", which provides end user and operator benefits including on-demand self-service, broad access across multiple devices, resource pooling, rapid elasticity and service metering capability.

The major models of cloud computing service are known as software as a service, platform as a service, and infrastructure as a service. which we will discuss later. These cloud services may be offered in a public, private or hybrid network.Google, Amazon, IBM, Oracle Cloud, Rackspace, Salesforce, Zoho and Microsoft are some well-known cloud vendors.

The cloud computing allows companies to reduce infrastructure costs, and focus on projects that differentiate their businesses instead of infrastructure.Cloud providers typically use a "pay as you go" model. This can lead to unexpectedly high charges if administrators do not adapt to the cloud pricing model.These days SME should understand the advantage of cloud computing and develop the organization to achive it goal.
