Different Elements

Till now we have learned what is Microservice and what are the basic needs of it above the modern MVC architecture. In this chapter, we will learn the different elements of this architecture that are equally important for a service.

Categories of Services

By the name Microservice, we assume that it will be a service that can be consumed over HTTP protocols, however we need to know what kind of services can be build using this architecture. Following is the list of services that can be implemented using Microservice architecture.

Platform as a Service [PaaS] − In this service-oriented architecture, the platform is given as a tool which can be customized according to the business needs. PaaS plays an important role in mobile application development. The greatest example of PaaS is Google App engine, where Google provides different useful platform to build your application. PaaS originally develops to provide a built-in architecture or infrastructure to developers. It reduces the higher level programming complexity in dramatically reduced time. Following is a snapshot of Google provided PaaS.

Google Cloud Platform

Software as a Service [SaaS] − Software as a Service is a software licensing business, where the software is centrally hosted and licensed on a subscription basis. SaaS can be accessed mainly through the browser and it is a very common architecture pattern in many business verticals such as Human Resource Management (HRM), Enterprise Resource Planning (ERP), Customer Relationship Management (CRM), etc. Following screenshot shows examples of different SaaS provided by Oracle.

Common Infrastructure Services

Infrastructure as a Service [IaaS] − Infrastructure plays a good role in IT industries. Using cloud computing, some of the organizations provide virtual infrastructure as their services. IaaS is very helpful for bringing agility, cost-effectiveness, security, performance, productivity, etc. in software development. Amazon EC2 and Microsoft Azure are the biggest examples of IaaS. The following image depicts an example of AWS, where the data center is provided as IaaS.

Data Center Services

Data as a Service [DaaS] − Information technology deals with data and some of the top industry leaders believe that data will be the new sustenance of the society. DaaS is a type of service where data is shared with business conglomerates for research and analysis. DaaS brings simplicity, agility, and security in the data access layer. Following is an example of Oracle Data cloud, which can be accessed or licensed for your own business needs.

Oracle Data cloud

Back End as a Service [BaaS] − BaaS is also known as MBaaS, which means mobile back-end as a service. In this type of service, backend of the application will be provided to business units for their own business ventures. All push notifications, social networking services fall under this type of services. Facebook and Twitter are examples of well-known BaaS service provider.

Security

When it comes to dealing with tons of customer data, security plays an important role. Security issue is associated with all kinds of services available in the market. Whatever the cloud you are using – private, public, hybrid, etc., security should be maintained at all levels. Entire security issue can be broadly sub-divided into the following parts −

  • Security issue faced by service providers − This type of security issue is faced by the service providers such as Google, Amazon, etc. To ensure security protection, background check of the client is necessary especially of those who have direct access to the core part of the cloud.
  • Security issue faced by consumers − Cloud is cost friendly, hence it is widely used across industries. Some organizations store the user details in third party data centers, and pull the data whenever required. Hence, it is mandatory to maintain security levels such that any private data of one customer should not be visible to any other users.

To prevent the above-mentioned security problems, following are some of the defensive mechanisms used by organizations.

  • Deterrent Control − Know you potential threat to reduce cyber-attack.
  • Preventive Control − Maintain high level authentication policy to access your cloud.
  • Detective Control − Monitor your users and detect any potential risk.
  • Corrective Control − Work closely with different teams and fix the issues that arise during the detective control phase.
