Can Hybrid Cloud Solve SaaS and PaaS Related Integration Issues?
Cloud computing is an internet based computational process that enables on demand sharing of data and resources between multiple computers placed at remote location. It introduces network-based services through virtual devices that are replicated on real machines. Cloud computing provides multi-faceted service model that includes Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS), IT as a Service (ITaaS), Backend as a Service (BaaS), and Desktop as a Service (DaaS).
SaaS is a cloud-based application that is in the form of a software delivery model in which software and the related data are provided through the cloud. Users can access SaaS through the internet, usually through a web browser. It generally minimizes IT support costs, provides more frequent customization, aids collaboration, and allows agile software development. PaaS is a cloud-computing model that provides applications on the Internet. It can be defined as a platform-based environment that provides quick and easy creation of web applications without any complexity of buying the software and maintaining the infrastructure. PaaS is very useful when multiple developers are working on the development of a project or when external entity requires interaction within the development process.
Cloud service users reported that PaaS and SaaS create more application integration problems than other service models, including private IT setups. These problems resist cloud services from getting the maximum potential out of it. Hybrid clouds help to overcome these problems by creating a static platform for the deployment of integrated applications, leveling the utilization of integrated or deployment tools, and to guide the application development and lifecycle management practices for integration optimization. However, it is compulsory to practice perfect hybridization or else the result can go against the expectation.
Application integration is defined as the process of linking application components to connect workflows along with user access optimization of productivity tools. Approximately each company operates on application integration with their internal IT resources. Most of the currently used tools are componentized in a specific way by presenting an application server along with a web server to various mobile apps or web browsers.
Hybrid cloud technology addresses the integration issues of PaaS and SaaS by elevating the overall integration to an effective level. The company owned IT resources needs private cloud technology and hybrid cloud technology to wrap up internal and public-hosted resources in a way to achieve effective implementation. The first step while deploying static application is to join resources to make connections through directories and URLs. The integration of dynamic elements is the first step of finding free resources because presuming the occurrence of components will not work.
The directory-driven deployment and integration tools meant to find dynamic components can be utilized to integrate applications either in or out of the cloud. It works well for all cloud service models, but companies do not use them because they can’t leverage dynamic resources before the cloud. While resorting to the private cloud, company’s infrastructure will constrain to use techniques and tools of dynamic integration to solve problems related to integration issues.
The implementation of hybrid cloud platforms for the applications solves the integration issues, but it generates uncertainty over the deployment structure of private cloud, which is not a sustainable process. The number says that less than 20 percent of the companies favor private cloud over virtualization, so adopting cloud friendly integration tools is a better option for application integration support, without the implementation of hybrid cloud. It raises two essential questions i.e. what to look in cloud friendly integration/deployment tools and which is the best time to build a hybrid cloud for the company?
The company owners find private cloud more useful because it significantly benefits applications from the dynamic resource assignments. An organization needs to test its supported virtualization tactics and adoption of dynamic tools for moving virtual machines. If a company passes the test then they can adopt private cloud technology for application availability or resource efficiency reasons, and the shift towards hybrid cloud would only enhance their private cloud transition. If an organization fails in any of the tests than it needs to make changes in its infrastructure; making it suitable for cloud friendly deployment and integration.
The utilization of PaaS cloud components assures execution of resources in the cloud, but it is not a sustainable process because cloud deployment is not possible by only using standard management tools. In the SaaS components, the resources are never deployed but they need to be purchased and integration must be done in the same form as its APIs. All of this compatibility with cloud integration tools fits the DevOps model. Software vendors or developers describe the application deployment in the form of an abstract model or script and it provides required elements for the integration process. Among the whole market of commercial and open source solutions, DevOps tools are the only one that support both static internal resources and dynamic cloud resources and the validation can be done through feature reviewing and pilot testing. The use of cloud compatible integration and deployment tool along with the hybrid cloud solves the SaaS and PaaS integration problems.
In most of the cases, the deployment of hybrid cloud solves the issues related to SaaS and PaaS validation, but “hybrid DevOps” scales high, as it is a more reliable solution for the problems occurring during SaaS and PaaS implementation. Integration issues can be a deciding factor for committing to the hybrid cloud strategy of enterprises, but it can’t fully justify the move of hybrid DevOps selection. IT professionals need to understand all benefits company will get after implementation of hybrid cloud that too before starting the selection procedure and by sidelining goals and problems of application integration.
