In general, when the term Cloud computing is used, it references the delivery of hosted services via the Internet. Cloud computing was a term derived from the cloud symbol used in flowcharts and diagrams to represent the Internet. What are the cloud computing layers architecture?

Cloud Computing Network Topology

What does Cloud topology mean? This relates to where your Cloud is hosted, which is one of the most important decisions that you have to make when moving to the Cloud. Why? Because it has tremendous impact on the security, costs, and control of your deployment. What are the common topologies?

Public Cloud

This is the most common and cost-effective way to host servers. The hardware and infrastructure are owned and managed by third parties so you pay for the computing resources without having to worry of what goes on in the background.

Dedicated Private Cloud

In this topology, all servers run on virtual machines in hardware that you own and control. The hardware is normally stored within datacenters that are inside your internal network. Since it is the most expensive infrastructure, it is normally suitable for larger organizations that require specialize security and privacy.

Managed Private Cloud

You own and control the hardware components that are hosted on external sites and managed by third parties. This allows you to take advantage of security and control benefits commonly found in dedicated private Clouds but without having to maintain an entire datacenter.

Hybrid Cloud

This delivers access to the benefits of public Cloud combined with the security and control delivered by private Clouds.

Cloud Computing Software

Did you know that there are a couple of options available to you when you avail of Cloud computing? These options are commonly in the form of software that are broken down into three main categories.

Infrastructure as a Service (IaaS)

This relates to the hardware necessary to execute the job. In this context you are paying for the parts and pieces that you need in order to take advantage of the benefits of the Cloud to run your applications.

Platform as a Service (PaaS)

With this option, the infrastructure is supplied by the vendor so you can focus on the deployment and management of the applications that you need. This frees you up from the need to buy the hardware, update the software, and prepare for capacity increases.

Software as a Service (SaaS)

This is the delivery of the entire Cloud package that includes the infrastructure, platform, and application. This completely frees you from all the necessary concerns in running the Cloud so that you can focus all efforts on the core competencies of your company.

What is Cloud Management Platform?

This describes the integration of products that are delivered for the management of private, public, and hybrid Cloud environments. The products must incorporate self-service interfaces, enable metering and billing, provision system images, and include workload optimization using established policies.

Advanced offerings can integrate with external management systems of enterprises including service catalogs allow enhanced resource management, and support configuration of network and storage resources. There are provisions for advanced monitoring to improve availability and performance.

Human Resources Cloud Computing

Why does human resources Cloud computing make sense? The implementation of this type of system eases some of the stresses associated with the growth of businesses and its human resource needs.

Using Cloud for human resource will provide first of all increased mobility and flexibility for your manpower. Second, it becomes easier to institute implementation and innovations. Lastly, Cloud will ensure data safety when it is properly and diligently entrusted to a reliable host.

Cloud Computing Security Issues and Challenges

Despite perceived benefits, there are a couple of reservations to the implementation of Cloud computing. This unwaranted skepticism is keeping the Cloud from being recognized and adopted by some organizations. What are these issues and challenges that concern them?

Security

One of the most common concerns that has hampered Cloud acceptance, it is brought about mostly by the lack of understanding of the security protocols of the technology.

Many organizations are still uncomfortable with having their data applications, and other resources residing in storage spaces that are physically beyond their reach even though the reality is they are much more secure in a quality cloud environment.

Costing Model

Some organizations feel that despite the reduction in infrastructure costs, Cloud migration will increase other related costs like data communication for example. This is not usually the case.

Service Level Issues

These arise when the host provider fails to deliver the ensured quality, reliability, performance and availability promised by the technology. Obviously, this emphasizes the need to entrust core business functions to reliable service providers.

Interoperability Issues

Interoperability ensures seamless transmission of data between the Cloud and local applications. When this is not achieved, or if the levels of interoperability are not present, then organizations can face problems in the deployment of needed services. Again, the need for selecting a quality cloud provider.

Taking all of these into context gives you a better understanding of the Cloud computing layer architecture. To make sure that the security issues and challenges are met head on, it is best to select a reputable cloud service provider. Contact Keyed Communications LLC now.
