Calculating the True Cost of On-Premise and Cloud Software Investments As Cloud technologies continue to evolve, more and more software buyers are seriously evaluating software as a service (SaaS) solutions against on-premise offerings. While there are many factors that influence which deployment model is best for any particular business (e.g., ability to manage IT internally and speed of deployment) the cost of the system is often a key factor. But comparing the true cost of a Cloud-based system against an on-premise system can be time-consuming and is often a complex undertaking. For instance, most buyers understand that on-premise licenses are

The 5-3-2 Principle of Cloud Computing: An Easier Approach Even though, cloud computing has become exceedingly common, the fact remains that people seem to have differing opinions when it comes to its definition. The issue is not the lack of definition or the lack of an agreed coherent one, but rather the lack of apparent direction. Cloud computing is an extremely large topic, but it is being used in very specific ways. In the same vein that makes it hard for people to stay on the same page when talking about general computing without agreeing to something specific, people need
Cloud Computing For Small Businesses And Why Penetration Remains Low Past 2012 In the last decade, cloud computing has become a hot topic, both in the media and at individual level. It’s estimated that close to 80 percent of all modern businesses use a form of cloud computing. The most surprising thing here is that most of them don’t even know they are using it. This has denied most of these businesses a chance to move forward, compete with peers, and grow. In the face of the benefits cloud computing offers to your business, the choices are wide open. However,
Security And Management In The Cloud Though there are various challenges involved in maintaining a cloud service, one of the major challenges that organizations face is security management. The advent of global computing represents cloud computing in totality. This has transcended boundaries, not just nationally, but also internationally. This same globalization is another challenge that has emerged for cloud technology, because traditional security models do not apply in the cloud infrastructure. Let us take, for example, firewall infrastructure. The very invention of firewalls in traditional systems was meant to provide “blocking-security” for single hardware devices. However, with cloud computing models,
What Is Cloud Computing? Yes, Another Perspective – Part 2: CLOUD COMPUTING MODELS Continued From Part 1 Cloud computing has several deployment models that are adopted according to need and requirement. Each configuration is implemented according to specific circumstances and necessities. In the following paragraphs, these techniques will be discussed one by one while outlaying their general purpose and structure. Public cloud is a model which explicitly defines cloud computing in its most traditional and grass-root essence. The utilities are provided by a vendor or any third party service provider. The equipment required for providing these services are installed by
Database Services on a Private Cloud For database environments, the PaaS cloud model provides better IT services than the IaaS model. The PaaS model provides enough resources in the cloud that databases can quickly get up and running and still have enough latitude for users to create the applications they need. Additionally, central IT management, security, and efficiency are greatly enhanced through consistency and economies of scale. Conversely, with the IaaS model, each tenant must build most of the stack on their own, lengthening time to deployment and resulting in inconsistent stacks that are harder to manage. A private cloud
Practically Speaking About Cloud Computing: IT Infrastructure Introduction: For more than two decades now, IT Infrastructure remains as the backbone of business. This business that we mention here can be a large enterprise or a small and medium business or a tiny business or even an individual’s business activity. There is no stopping of the part played by IT infrastructure. However, because of macro economic conditions, the way IT infrastructure is deployed is influenced by new forces. This is where cloud computing is coming in to the picture; and of course starting to play a major role! More than anything
Hybrid Clouds Hybrid? True that it is getting noisier with cloud computing. And in clouds, hybrid cloud is making more noise! In giving the meanings to hybrid, dictionaries mention that it is an offspring of two animals and more similar synonyms. Going further, they use the word heterogeneous in origin and composition, two different types of components doing the same function. Hybrid clouds, as we know, depict the combined use (benefits/problems) of private cloud and public cloud. Are there two different types of components in Public and Private Cloud? Are they heterogeneous in nature? Leaving these questions to geeks (and
