DevOps Microservices And What Challenges Are Faced In Implementing A Microservice Architecture

Microservices are compact distributed services with loose coupling. As a response to the scalability, independently deployable, and innovation issues with a monolithic architecture, microservice architecture emerged (Monolithic applications are typically huge – more than 100,000 lines of code). It enables you to take an extensive application and divide it into small, easily manageable components with clearly defined roles. Microservices. Despite having been created in 2009, they began to gain notoriety and popularity in the years 2014 and 2015, when the market realized that the architecture model was, appealing for cloud applications. Since then, especially since the world is heading toward cloud computing, it has solidified itself as a common standard and a developer preference.

It is viewed as the fundamental component of contemporary applications. Microservices are small, independent programs that can be built in a variety of computer languages and frameworks. One can think of microservices as a subset of SOA (Service Oriented Architecture).

What are Microservices?

Software is made of small, autonomous services that communicate over well-defined APIs within microservices' architectural and organizational framework. Small, independent teams are the ones that own these services.

Microservices architectures enable innovation and speed up the time to market for new features by making applications easier to scale and quicker to develop.

A single application comprises numerous loosely connected, independently deployable, smaller components or services, according to the microservices (or microservices architecture), a cloudnative architectural approach.

The Benefits of Microservices

  • Greater Scalability
    One of the microservices' most important advantages is scalability. Increases in user traffic impact any part of a monolithic application. For instance, the additional load may lead to the complete application crashing if website users make more product purchases on an ecommerce site. The front-end, back-end, database, and other components all experience overload simultaneously since all monolithic components share the same server resources.
    On the other hand, in a microservices application, each service has specific resources assigned to it. Therefore, only the front-end services will require additional resources when website traffic increases. For instance, the database won't be impacted because it operates as a distinct service with autonomous resources. Users will always have a great experience because of the increased scalability, which helps reduce outages.
  • Better Fault Isolation for More Resilient Applications
    Because each microservice in a microservices architecture operates independently from the others, the failure of one service is less likely to have an adverse effect on other components of the program. Developers must nevertheless safeguard the application from a shutdown caused by a dependency failure because big distributed microservices architectures frequently have several dependencies.
  • Programming Language and Technology Agnostic
    Developers can integrate any language-programmed microservice when building a microservices-based solution. Additionally, they can link microservices that are operating on any platform. Using the programming languages and technologies that best suit the requirements of the project and the skill sets of your team is made possible by this increased flexibility.
  • Better Data Security and Compliance
    The ability to take a more granular approach to data protection is one of the essential advantages of microservices for enterprises. It is simpler to deploy security measures at the service level because each service has a specific task. Compared to keeping all data in a single monolithic database that is accessible by the entire program, this strategy is significantly more secure.
  • Faster Time to Market and "Future-Proofing"
    Application development and upgrades are made more straightforward and quicker thanks to the pluggability of a microservices architecture. Microservices are easy to create or modify, and once they are plugged into the architecture, there is less chance of coding conflicts and service interruptions. Teams don't need to be concerned about coding conflicts or wait for slowermoving projects to deploy their application portion because each Microservice is independent.

Challenges of Implementing a Microservice Architecture

Increase scalability and speed up feature delivery by putting microservices into use. Many obstacles must, however, be taken into account. Implementation success will be increased by tackling these problems head-on. Below are a few typical issues that need to be resolved.

  • Greater Complexity: The potential for increased complexity is one of the microservice architecture's most significant drawbacks. This is so that each Microservice, with its codebase, database, and dependencies, can operate independently. Managing and keeping track of this can become complex very fast when you have a lot of microservices. Your microservice management approach must clearly address this issue if you want to succeed. This is an example of having distinct service boundaries, versioning your services, and adopting serverless or container technologies to simplify deployments.
  • Communication Overhead: Another drawback of microservices is the communication overhead they bring. For each Microservice to do its tasks require communication with other Microservices. Network traffic can grow as a result, and latency problems may arise. Your communication protocols must be carefully planned to address this issue, and you should use caching or message queues as necessary. Another option for decoupling your services is to use asynchronous communication.
  • Testing and debugging challenges: Due to their distributed nature, microservices can be challenging to test and debug. Separate tests and debugging sessions must be conducted for each microservice from those conducted for the others. This can quickly become costly and timeconsuming when you have a lot of microservices. The best testing tools and methods, like contract testing and test-driven development, must be used to address this issue (TDD). To imitate dependency behavior during testing, you should also use mocking frameworks.
  • Lack of Standardization: Since each Microservice is created individually, there is no one-sizefits-all method for constructing them. As a result, your microservices may be designed and implemented inconsistently, making it harder for new team members to understand your application and more difficult to manage over time. One method to address this issue is by creating standards for your microservices. This also involves coding standards as well as directory layouts and communication methods. By following standards, your microservices can be made consistent, simple to comprehend, and easy to manage.

Best Practices for Building Microservices

It can take time to develop and implement microservices. These best practices for creating and deploying microservices will help you stay clear of typical problems and make the most of this architecture.

  • Maintain Focused and Compact Services: By dividing a monolithic application into several smaller, independent components, microservices enhance modularity, one of their key advantages. But in order to remain manageable, services must be kept concise and narrow. Each service ought to be responsible for just one thing: a solid general rule.
    Carefully define service interfaces: How microservices communicate with one another is another crucial factor to consider while developing microservices. For service interfaces to be welldocumented and simple, thorough definition is necessary. Additionally, consider utilizing industry-standard protocols like HTTP or GRPC so that services can connect across all platforms and computer languages.
  • Use an API Gateway: An API gateway is a proxy server that offers clients a single entry point to various services. Your design can be made simpler and perform better using an API gateway, which also decreases network traffic. An API gateway can offer additional functions like authentication, rate-limiting, and monitoring.
  • Use Version Control for Services: Version control is critical to the success of any software development project, but it becomes much more important when dealing with microservices. This is so that each service may be managed independently, as each one has it’s codebase. To keep track of changes and ensure each service can be deployed independently, you should use a version control system, such as Git.
  • Implement continuous integration and delivery (CI/CD): Continuous Integration (CI) is the process of frequently integrating code changes to ensure that there is always a current functioning version of the codebase. A step further is taken by continuous delivery (CD), which automates the deployment process to make it simple and rapid to release code updates into production. In a microservices architecture with several codebases to maintain, CI/CD helps to ensure defects are detected and fixed promptly.

Infrastructure as Code

It used to be challenging to manage IT infrastructure. Every piece of hardware and software required for the operation of the apps had to be manually managed and configured by system administrators.

The situation has drastically changed in recent years, though. How businesses plan, create, and maintain their IT infrastructure has changed and improved thanks to trends like cloud computing.

The term "infrastructure as code" is one of the critical elements of this trend, and that is what we'll be discussing today.

Managing and providing infrastructure with code rather than manual procedures is known as infrastructure as code (IaC).

It is simpler to change and share configurations with IaC because configuration files with your infrastructure specifications are created. Additionally, it ensures that the environment you furnish each time is the same. IaC facilitates configuration management and helps you prevent ad hoc, undocumented configuration changes by codifying and documenting your configuration standards.

IaC places a high value on version control, so your configuration files should be subject to it just like any other source code file. By automating the deployment of your infrastructure as code, you can also break it into modular components that may be put together in many ways.

What is infrastructure as code?

Instead of using physical hardware setup or interactive configuration tools, infrastructure as code is the technique of managing and provisioning computer data centers through machine-readable specification files.

Benefits of infrastructure as code

It has always taken a lot of effort and money to provision infrastructure manually. At present, virtualization, containers, and cloud computing have replaced physical hardware in data centers as the primary means of infrastructure management. At the same time, this may still be a factor for your company.

As more applications are pushed into production every day thanks to cloud computing, the number of infrastructure components has increased. Additionally, infrastructure must be able to be quickly spun up, scaled, and taken down. Managing the size of today's infrastructure without an IaC approach is getting more challenging.

IaC can assist your company in managing its requirements for IT infrastructure while also enhancing consistency, minimizing mistakes, and requiring less manual configuration.


  • Decreasing costs
  • Rapid deployments will increase
  • Fewer mistakes
  • Boost consistency in the infrastructure
  • Config drift must be eliminated


Infrastructure as code tools

In many cases, IaC can be achieved using server automation and configuration management tools. Also available are IaC-specific treatments.

A few well-liked options are as follows.

Automation Platform for Red Hat and Chef Puppet

  • Saltstack
  • Terraform
  • The AWS Cloud Formation

Why does IaC matter for DevOps?

Continuous Integration/Continuous Delivery (CI/CD) and DevOps methods implementation include IaC significantly. Since they can run a script to have their infrastructure ready to go, developers no longer have to do the majority of the provisioning work thanks to IaC.

Sysadmins won't have to spend their time managing laborious manual procedures, and application deployments won't be delayed while the infrastructure is being built.

A setting must be consistent for it to be automated. When the development team delivers applications or configures environments in one way while the operations team deploys and configures in another, automated application deployments are ineffective.

The alignment of development and operations teams through a DevOps methodology reduces errors, manual deployments, and inconsistent behavior.

Because both teams can utilize the detailed description of the application deployment, IaC supports a DevOps strategy and aids in bringing development and operations closer together.

The same deployment procedure should be employed for all environments, including your production environment. When IaC is employed, the same environment is created each time.

The production environment will be constant thanks to IaC, which also eliminates the need to maintain separate deployment environments with special configurations that can't be automatically replicated.

Infrastructure in IaC is treated with the same respect as DevOps best practices. To apply the same testing and version control to the infrastructure code, the same CI/CD pipeline used to develop applications may be applied to the infrastructure.

Monitoring and Logging

Log management is referred to as "logging." Events pertaining to the state of a system are gathered in logs, which are event records. For various systems, there are many different logs.

Consider a web application as an example. Logs can record any activity on the web service, such as a user connecting to the system, an HTTP error occurring, or a request for a server resource.

Rapid data collection means a high material and labor cost. In addition, the following actions must be taken in order for logs to be useful.

  • Choosing helpful information to retain and archive
  • Preserving the privacy and security of stored logs
  • Controlling the quality of log data by examining and incorporating missing data into the logs
  • Examining logs (often confused with application monitoring)
  • Adding the IP address of the logs' creator to events to contextualize them further
  • User is worried
  • Concerned feature
  • Error information

Contextualizing the logs, which identifies which data should be retained and which should be destroyed, requires the most knowledge and understanding of the system being monitored. Additionally, a lot of human time must be spent on this endeavor.

After all of these steps have been taken, the logs will enable examining an application malfunction to prevent it from occurring again. In the event of an attack, this will enable the identification of the key players. In addition, it will be possible to identify the capability that has been misused, allowing for the correction of the error that facilitated the assault.

Monitoring or supervision of an application is the capacity to have both a current, global view of the application and a history of previous states for several elements.

  • Performance and response time of the various server resources
  • Integrity, ensuring that the content of online sites does not alter
  • Checking the application's availability will show whether it is up or down and fully operational.

Monitoring is essential for spotting any server performance issues, as well as for real-time threat detection. If a server needs high availability, tracking user behavior enables developers to determine which features of the program are resource-intensive and likely to cause delays. A denial of service effort may be ongoing during an attack if the service receives many connections. An alert could enable the security team to take action, such as blocking IP addresses making too many or too fast established TCP connections or partial TCP connections.

A global supervision tool must be utilized to consolidate the various logs in order to discover these anomalies. This instrument must question the services that need to be watched in real-time. It can be based on several measures, including CPU load, the number of concurrent connections (TCP, UDP, application, etc.), server failures, a simulation of contact with the program, network load (QOS, latency, ping), and attempts of connections banned by the firewall (Nmap detection).

Events must be able to be created under this element's control (alerts). These factors represent important state shifts. This can be caused by an excessive CPU load, a push to a repository, a build mistake, or an excessive number of concurrent TCP connections. Setting criticality levels for the events is then required for an effective follow-up. As with a ticket management program, this enables you to process them in the order of priority.

Because the monitoring system uses logs as its primary data source and effective monitoring requires high-quality logs, logging and monitoring are frequently conflated. However, monitoring should not be mistaken for log analysis. Monitoring is ongoing labor, whereas log analysis is post-incident activity.

Evaluating its Logging and Monitoring System

It is now required to assess the effectiveness of the various systems after they have been implemented.

The absence of alerts over an extended period of time is a straightforward first indicator to investigate. There is always some anomaly to be recorded, even if it is just a small fact. Additionally, if a known issue with the information system exists and the monitoring system does not issue any alerts, a configuration issue with the system is unavoidable.

Running a vulnerability scanner on your server and application, such as OpenVas or Burp, would be a valuable test. This kind of scanner should generate multiple notifications. Additionally, you can add details to the raised warnings based on the tests they run. For instance, if you set up a scanner to test command injection on a feature, the alarms triggered for functionality misuse may be categorized as attempts at command injection.

Once these internal checks and changes have been made, one or more application penetration tests are excellent for your monitoring systems. Indeed, they frequently make it possible to draw attention to potential issues. A pentester needs help to assess how diligently the audited organization manages the server's logs. Every action a pentest takes must cause your system to issue an alert.

Communication and Collaboration

Good communication and collaboration skills can significantly affect the way a company functions. Employees who know how to use these skills are usually more productive and can work better in a team. This article explores various communication and collaboration skills, discusses their importance, and outlines how they can be improved.

What are communication and collaboration skills?

Communication and collaboration skills help you deliver verbal and written information to your colleagues and receive information from them effectively. These skills make it easier to work in a team and achieve collective goals. Collaborative skills allow teams, customers, and partners to work alongside each other efficiently. A team may collaborate by delegating tasks to suit each member's talents and interests.

Examples of communication and collaboration skills

Here are some examples of communication and collaboration skills.

  • Attentive listening
    Attentive listening allows you to capture the essential details during a conversation. While working in a team, this skill can help you understand instructions better and gauge the opinion of other team members to build positive working relationships. Attentive listening can also help you to identify, prevent and solve challenges promptly.
  • Interpersonal skills
    You can use interpersonal skills to optimize collaboration within your team. These skills allow you to interact with others, build trust, manage and resolve conflict, and develop long-term solutions.
  • Time management
    Managing your time and the team's time well helps you complete projects and tasks promptly. You can maintain good time management using your communication and collaboration skills by regularly communicating timelines and deadlines to co-workers. You can keep your team organized and delegate tasks more efficiently with excellent time management.
  • Critical thinking
    Collaboration encourages critical thinking through collective discussions, idea clarification, and debate. Critical thinking can help you articulate your opinions and ideas more clearly and respond to challenges methodically, i.e., by reviewing facts and assessing possible outcomes to choose the most effective solution.
  • Decision-making
    Team members collaborate to make informed decisions about a situation that could affect the team, department, or company. Communication and collaboration skills are needed to communicate facts, ideas, and opinions that ultimately assist decision-making. Collaborative decision-making can help you firmly establish collective goals and strategies to accomplish them.
  • Adaptability
    Adaptability refers to your ability to adjust your activities, programs, or methods in response to a change. It allows you to interact with people more productively and avoid or moderate challenges. If you are adaptable, you can assess people's preferences and speak to them in the way they prefer.

Importance of communication and collaborative skills

The following points outline the benefits of communication and collaboration in the workplace.

  • Help with problem-solving
    Collaboration and communication skills facilitate fast problem-solving in an organization. Working together as a team encourages brainstorming and sharing ideas that can help you find solutions.
  • Allow employees to learn from each other
    Forming a team that contains employees with different types of work experience and qualifications gives individuals a chance to learn from each other. It allows your team to expand their knowledge and skills. Your co-workers may feel empowered when an organization allows them to share ideas and learn from one another. Collaborating with colleagues on a project can be a valuable learning opportunity.
  • Increase employee productivity
    Working as a team can make completing projects and meeting deadlines easier. Team members can obtain the help they need more efficiently when a company promotes clear lines of communication. Good collaboration can also help members understand each other's strengths, meaning they can question experts in a specific area. Employees may then complete a higher standard of work within the assigned time.
  • Create a positive work environment
    Good communication and collaboration among team members help ensure that team members understand each other. It also promotes trust and respect among employees. A positive workplace culture helps to boost morale and enhances employee retention. Employees who work in a strong team may experience higher levels of job satisfaction.
  • Help boost confidence and morale
    Employees trust each other more when good relationships between team members and departments exist. This can increase confidence and the overall productivity of the firm. Regular working with people outside your team or department can be one of the most effective methods for developing trust. Your team may feel more comfortable working with colleagues from other departments when the company's morale is at its strongest.

How to improve communication and teamwork skills

Improving these skills can be crucial for helping you to relate to your colleagues and increase your effectiveness. The following are ways in which you can improve your communication and teamworks

  • Be transparent
    Being open about the challenges your organization or team faces can help improve company collaboration.

Reinforcing effective communication strategies can make it easier for co-workers to share their thoughts when working and speaking with management.
  • Listen to your team members' views
    Listening is a vital aspect of communication in the workplace when developing professional relationships. Respecting each team member's viewpoints, being heard, and promoting active input can significantly improve a team's capacity for collaboration. Allowing a team to discuss each other's ideas and opinions creates a space conducive to effective communication.
  • Use video conferencing
    Video conferencing makes it easy to connect with your team when you're working remotely. Face-to-face conversations with another team member can strengthen communication and prevent non-verbal signals from being missed.
  • Set targets
    Defining each team member's duties and expected outcomes will improve collaboration and communication. Having clearly defined roles allows team members to ask questions, feel more confident, and ultimately feel accountable for their work. When each team member has a clearly defined position, they may be more aware of what they can contribute to the group and feel proud when they complete a task.
  • Obtain feedback
    Feedback is an excellent sign of how well a company communicates and collaborates. Effective feedback includes keeping each team member's and the team's best interests in mind by encouraging them to provide feedback on how the company can improve.
