Microservices are making all the difference in business organizations, but is it all good to go with? What are the barriers that may prevent you from taking advantages of microservices? Or even its adoption?
Since its inception in 2011, microservices are taking leap over many business solutions in application development industry. There is much debate on its benefits and potential roadblocks in the way to success for business organizations. Microservices in Canada are the mainstream architecture in managing your business workflow efficiently. Almost all the fields are either implementing or in research process for integrating microservices, with proved success in Canadian marketing, banking, finances, retailing, and data analytics. You must be wondering exactly what microservices offer? Do you need to have microservices all from the beginning of your company or product? When to adopt microservices? Does it matches with your organizational and product needs? Is there any necessity with moving to serverless computing? What can prevent an organization to incorporate microservices?
Looking for your answers? Let’s see, some of the reasons to adopt microservices and the road blocks in the ways:
Why Adopt Microservices?
Microservices are considered as variants of Service Oriented Architecture that are designed with loosely coupled services. With decentralized approach microservices enable deployment, development, and testing much easier with high level of modularity. It is much easy for the Canadian developers to add, change and maintain the system modules, rather than a whole system. It consists of lightweight protocols and fine grained services.
Traditional monolithic application uses a centralized approach, where a single codebase is used to create the entire application. Such an architecture works best for desktop based application, but not in today’s digitized world. In highly connected and information-based world, you need the heavy data which is stored at different servers around the globe. However, this data is needed to be accessed by users so you need to connect them with a range of devices and servers. Also, with frequent advancements, you also need to update the system very often.
Microservices allow you to update and change the system with better testing and performance quality, without really shutting down for the users. You cannot do this with the single codebase system where functions are closely attached. The one time investment on traditional system is very high and if you need to make changes it will cost a lot, whereas with microservices it’s easy and cost effective. There are many significant reasons why you should adopt the microservices, along with the following benefits:
Highly decentral and Resilient
Microservices adoption makes your services decentralized so that each of the services play their role separately. Much centralized architecture creates troubles in times of maintenance and turns out as a failure, while microservices makes it smooth with users won’t really notice if there is maintenance going on. Altogether, using microservices has minimum effect on the entire system.
Enhance Scalability, Availability and Performance
When each service act as a separate entity, it is possible to scale-up a service or its function individually, without disturbing other components or the architecture as a whole. You can easily enhance the availability and performance of the services by integrating different servers to different services or functions. Especially, if there are some business critical functions that your wish to run seamlessly, your performance can definitely take the boom with microservices.
A well-planned service plan may help you deal with the scalability automatically, which is effective in balancing the load. What you need to do is developing each of these services with separate back-ups. In this way, you will maintain and restore them without having any impact on the entire system. For this to be possible you need a design that prevents any outside malevolent tampering as well as keep the process of development automated.
Choose the Appropriate Tools
Microservices enable you to select the best option for your services and tasks with convenience of not relying on the single server or vendor. Each service may operate within its own framework by incorporating the most suitable tools required to make the architecture completed with efficiency as well as enable it to connect with other service (being operated under similar or different serverless computing service) when needed.
Quick Access to Market
With all of your services being deployed and tested independently, it is easy to increment smaller changes in the application without waiting for it to launch. You can make a faster go-into the market and keep modifying your features after it is launched. With the loosely coupled microservices you don’t have to rewrite your entire application program to improve or add some features.
Microservices can make debugging and testing much easy, than conventional architectures. It makes your application system error-free, because you are working with small modules and it is possible for you to scan bugs and errors in these components more efficiently than the one whole application at a time.
Cost, Time and Operational Efficiency
As you are able to deploy your system quickly, with each component being maintained regularly that ensures operational efficiency. There is less investment on the development team and time to market. Serverless computing helps you optimizing your resources such as you can utilize your development team’s effort and time on other tasks. You don’t need expensive machines for decoupling services and basic machines like x86 will do the work.
High Return on Investment
Return on Investment ROI is all you seek in the end of each year. Microservices may offer you best downtime and saves much expenditure on machines. Reduction in infrastructure cost, resources cost and time efficiency turns out in better ROI, than the conventional architecture.
Incremental Development and Continuous Delivery
With incremental development you build, test, and deploy your code continuously, as well as avoid reinventing the wheel by reusing the code from libraries. Microservices use Continuous Delivery Model to manage the application life cycle, while monolithic systems are based on teams working on discrete functions. In continuous delivery workflow, it becomes instant and easy as the team can operate and test the modules simultaneously for single service.
However, the promising microservices maybe, there are still some roadblocks in adoption of these architectures. So, let’s explore them:
Roadblocks for Microservices Adoption
It’s a fact that Canadian organizations those have implemented microservices have left behind those who have not yet considered its benefits. Besides, all of these admiring capabilities across several industries, there are problems that may not let you go with the microservices as the best option.
Rapid Provision and Deployment
You can rightly say that microservices is not the right option for every business due to its own ability to manage such services and capitalize on its architecture. Microservices follow the continuous delivery and incremental approach that keeps you on your toes for faster market availability and then continuous improvement. Thus, you must be able to deploy services or application quickly. Your staff should be ready to perform as required within the fast paced working environment to make the most of the advantages, otherwise it may turn out as a problem.
Infrastructure Management, Monitoring and Maintenance
As your infrastructure is running on multiple services, different teams may manage them simultaneously for APIs, platforms, and languages. You will need the robust monitoring and maintenance for your system to work effectively. It is to keep track of the services in case a problem may arise and you may be able to address solutions timely.
Adopt Devops Culture
Your organization and team members should embrace the devops culture and best practices in cross-functional way. In devops teams, all members are accountable for the system success and failure, contrary to traditional work environment where each member is hooked with different operational and production challenges, depending on their roles.
Everything is not as simple as it may seem in the microservices. The number of features and services increasing means new dependencies and new complexities will appear. Sometimes it might be impractical for you to respond to each tab so quickly. All solutions are not direct, some may be transitive. Obviously, your microservice architecture may handle a certain degree of faults for service unavailability, caching issues, network latency, and database errors. Thus, you must go for fault injection and resiliency tests.
Prepared for Failures
It is necessary for you to design your system to be prone with multiple failures such as unexpected responses, slow service, and system downtime. You must have the option B ready for all these problems, in exception to load balancing. Without crashing your system should still run even if one or few services are troubled, in case a failure occurs system uses degraded functionality.
Dependencies and Interconnections
To make the most of microservices, you must be familiar with what it is, how it works, and what you need to do to implement them? Microservices split your software application into small entities that may communicate via APIs to ensure produce continuity and performance. Although, components may act independently they have some functions overlapping so they must be supportive for inter-connections using the APIs. Which makes it important for you to test the inter-dependencies among the various microservices that are built separately before you go for a release.
Technically speaking, although microservices have certain level of independence, still they have some interdependencies that may require you to duplicate the similar functions. For instance, you need to update the library in microserviceA which uses the same library as microserviceB, if there is a change in something within microserviceB library. Therefore, businesses may like to adopt microservices for their bulky system that is hard to maintain and update.
Know the Right Time for Adoption
Developers may be able to improve resilience, reduce complexity in development, and make quick access to market with separate rebooting, isolation of many functions, and creating new versions of the product. This all can be achieved if your organization and team understands that splitting the architecture into decoupled microservices requires much effort and capability. Your organization must be at a certain level of complexity and scalability to incorporate such an architecture.
You must understand that operational complexity of the system increases with the level of splits it undergoes. Usually, you need to test codebases separately to check the operational stability and complications in synchronization releases. You can plan to adopt microservices right from the beginning of MVP development. So, you need the team with appropriate expertise to plan and build ahead for designing, implementation and maintenance of the system.
Planned Solutions with Microservices
You might pick-up the best microservices, but if you didn’t plan the solutions beforehand, it may lead to major problems and make your system unbearably complex. Although, it seems simple there is a high demand of expertise in team that is not achievable with professionals who are used to work with traditional application architecture. It is better to switch to microservices with better research and well-planned framework to avoid the horrible outcomes.
