These applications are generally customizable, though the customer need not be concerned with the underlying infrastructure or the development platform or the actual implementation. While the platform upon which the application is deployed might be hidden from the consumer, it is the source of the multi-tenant properties of SaaS and the customization capabilities offered to its consumers.
The underlying platform for Salesforce. Applications are the only component here. Whether the application is the result of building utility computing, followed by a platform, or it is simply an application deployed on a server, this is what users interact with. Users do not care how it was built, where it resides, or the compute resources required to deliver it.
They simply expect it to be available when they want it, responsive and well-performing enough to be useful, and expect it to be secure regardless of where, when, and how they access it. As we move up through the pyramid from the building blocks of infrastructure to the pinnacle of the application, the skill and knowledge necessary to build the components decreases.
This is simply because each layer can be built on top of the previous without having to fully understand the underlying layer. An organization with limited infrastructure skills can readily purchase IaaS from a vendor and build their own platform or several upon that infrastructure without needing the expertise to completely build the infrastructure from scratch. This has been happening for years in the managed hosting business. The organization does not have to be hardware or networking experts and therefore, as an organization, they require less technical expertise.
Ideally, an IT organization will build a set of services that fit the needs of the business organization. They can build an IaaS solution within their own data center, a PaaS or several on top of that and even deploy ready-made applications in a cloud context, satisfying the needs of the business in an agile way.
This enables them to react quickly to the ever-changing needs of the business. In a similar manner, business units can now deploy solutions based on their needs and level of technical competency. They can deploy SaaS solutions via an external cloud provider or rely on internally available solutions; or they can build apps upon platforms or deploy their own IaaS solution. The cloud architecture enables organizations to deploy solutions that naturally meet at the intersection of IT and business.
Given the dynamic and non-static mappings between the applications and the resources-regardless of whether the IT organization built the application from the ground-up to meet the needs of the business or the business simply deployed their own solutions-cloud architecture enables them to seamlessly integrate at the most appropriate point for the organization.
The organization, therefore, is able to maintain various elements of control for example, security and compliance while still providing the maximum level of agility to the business.
This newer dynamic cloud architecture may bring a wealth of new benefits, but it must still satisfy the basic mandates of enterprise IT and, if the internal systems are going to mesh with external ones, it must provide for consistent and reusable methods of interconnecting the divergent implementations at the cloud providers as well.
In order to achieve mass adoption within by IT, the cloud and the dynamic control plane must be an enterprise-class solution and not just theoretical or a hodge-podge of workarounds and unique implementations. When originally discussing the concepts of Infrastructure 2. Amongst these where an infrastructure that was scalable, adaptable, extensible, and manageable.
However, there are additional, basic fundamental needs of enterprise IT that must be taken into account. Any component that provides such comprehensive involvement in the applications and data must also be secure and be able to operate in real-time; it cannot degrade security or impede performance.
The dynamic control plane must always be available to connect users to the appropriate resources and it must do so in real-time without impacting performance. Despite the fact that the dynamic control plane needs to mediate and account for every user session and the movement of each application connection and each data access in order to be enterprise-ready, it must do so with little to no additional latency.
As was previously stated, the application and the user experience of that application is the final, ultimate goal of any IT architecture. Correctly balancing that user experience with the controls and policies required by the business is the ultimate goal of cloud architecture. Cloud computing is not a revolution. It is an evolution that has been ongoing for well over a decade, if not since the very beginning of electronic computing. The cloud is simply an architectural model that employs many of the same components used in datacenters around the world today in a more flexible, responsive, and efficient way.
The primary difference is in how these components are tied together with a dynamic control plane which helps enlighten and inform the architecture about the rapidly changing requirements of today's applications, data and clients. The dynamic control plane must be able to Intercept traffic as it traverses the cloud, Interpret the data and Instruct the cloud architecture on how to efficiently connect the user to the appropriate application instance.
However, in order to be truly ready for enterprise deployment, it must also be scalable, adaptable, extensible, manageable, and secure with real-time performance. And in order to support this dynamic environment the cloud must be built with these ideals in mind, with each component-such as IaaS, PaaS, SaaS, users, and applications-designed to work together and as part of the dynamic control plane.
There is no doubt that some concept of cloud computing will become the primary method of delivering business critical applications in the coming years.
There is little doubt that a move to cloud architecture will continue to provide the tools needed to better align business and IT. About the only thing that remains to be seen is whether the vendors and manufactures can deliver an enterprise ready dynamic control plane to bring the entire picture together to provide those benefits.

Updated January 10, With this diagram, you must then focus on what data is passed between systems — thus the need for strong DFDs — because someone will have to implement a solid design to pass that data. In addition, mapping out your process flows with swimlanes most likely with systems as the lanes , indicating where you move from one system to another will help you identify those integration points where people or data move between systems.
Does my data actually get passed so they can perform the next step on it? Archived Forums. Cloud Computing: Private Cloud. Sign in to vote.
Hi I am new to cloud computing, I want to know the following 1. How the cloud computing is configured? How much internet speed required to host or access the cloud environment? Included in the requirements are: World-class security - Provision world-class security at every level. Security is more than just user privileges and password policies.
It's a business imperative, especially for providers who are responsible for customer data. Cloud-computing platforms must have detailed, robust policies and procedures in place to guarantee the highest possible levels of: Physical security Network security Application security Internal systems security Secure data-backup strategy Secure internal policies and procedures Third-party certification Compliance, trust and transparency - Provide compliant, transparent, real-time, accurate service performance and availability information.
Clouds should provide customers with detailed information about service delivery and performance in real time, including: Accurate, timely, and detailed information about service performance data and planned maintenance activities Daily data on service availability and transaction performance Proactive communication Multi tenancy - Deliver maximum scalability and performance to customers with a true multi tenant architecture. A multi tenant architecture allows for high scalability and faster innovation at a lower cost.
