How to Implement Istio in Multicloud and Multicluster

Aggregated on: 2023-06-06 23:30:46

Today every application has microservices architecture where individual services are spread across public clouds and multiple Kubernetes clusters. Since all the communication of messages among services happens over the internet, it is very important to ensure the security of your data. You don’t want any malicious guy to read and record the data-in-transit (known as packet sniffing), or intervene in between the communication as someone you trust (IP spoofing), or perform a DoS attack such as bandwidth flooding or connection flooding, etc. The idea is security should always be developed in a layered approach to build defense in depth. When software engineers are developing containerized applications they need to think about security at Code, Container, Cluster, and Cloud levels (read 4 C’s of container security).

Introduction to Domain-Driven Design

Aggregated on: 2023-06-06 23:15:46

Domain-driven design (DDD) is an approach to software development that focuses on understanding the domain of the problem being solved, and using that understanding to guide the design of the software. This approach is particularly well-suited to microservices architectures, where services are designed to be small, autonomous, and focused on a specific business capability. In this article, we will explore how domain-driven design can be used to design microservices, and why this approach is beneficial for building complex software systems.

Why I Prefer Trunk-Based Development

Aggregated on: 2023-06-06 23:15:46

These days, distributed version control systems like Git have "won the war" of version control. One of the arguments I used to hear when DVCSs were gaining traction was around how easy it is to branch and merge with a VCS like Git. However, I'm a big fan of Trunk-Based Development (TBD), and I want to tell you why. With trunk-based development, all developers work on a single branch (e.g., 'main'). You might have read or heard Martin Fowler or Dave Farley talking about it. It was when I was working with Dave (around about the time that Git was rapidly becoming the "go-to" version control system) that I really saw the benefits of trunk-based development for the team, particularly in an environment that was pioneering continuous delivery (Dave was writing the book with Jez Humble while I worked with him).

Idempotent Liquibase Changesets

Aggregated on: 2023-06-06 22:45:46

Abstract “Idempotence is the property of certain operations in mathematics and computer science whereby they can be applied multiple times without changing the result beyond the initial application” [Resource 3]. The purpose of this article is to outline a few ways of creating idempotent changes when the database modifications are managed with Liquibase. Throughout the lifetime of a software product that has such tier, various database modifications are being applied as it evolves. The more robust the modifications are, the more maintainable the solution is. In order to accomplish such a way of working, it is usually a good practice to design the executed changesets to have zero side effects, that is, to be able to be run as many times as needed with the same end result.

Adding Mermaid Diagrams to Markdown Documents

Aggregated on: 2023-06-06 20:00:46

Mermaid is a trendy diagramming tool. A year ago, it was integrated into the Markdown rendering of GitHub. It is also integrated into several editors (see "Include diagrams in your Markdown files with Mermaid" for more information). What can you do, however, if you use a different editor? What if you want to use your Markdown document in an environment that does not integrate Mermaid yet? What can you do if the diagram is not Mermaid but PlantUML, Graphviz, or any other diagramming tool?

Understanding Data Compaction in 3 Minutes

Aggregated on: 2023-06-06 17:45:46

What is compaction in the database? Think of your disks as a warehouse: The compaction mechanism is like a team of storekeepers (with genius organizing skills like Marie Kondo) who help put away the incoming data. In particular, the data (which is the inflowing cargo in this metaphor) comes in on a "conveyor belt," which does not allow cutting in line. This is how the LSM-Tree (Log Structured-Merge Tree) works: In data storage, data is written into MemTables in an append-only manner, and then the MemTables are flushed to disks to form files. (These files go by different names in different databases. In my community, we call them Rowsets). Just like putting small boxes of cargo into a large container, compaction means merging multiple small rowset files into a big one, but it does much more than that. As I said, the compaction mechanism is an organizing magician:

Aggregated on: 2023-06-06 17:15:46

In this article, we will briefly describe and roughly compare the performance of various request-handling approaches that could be used in Spring Boot applications. Efficient request handling plays a crucial role in developing high-performance back-end applications. Traditionally, most developers use the Tomcat embedded in Spring Boot applications, with its default Thread Pool for processing requests under the hood. However, alternative approaches are gaining popularity in recent times. WebFlux, which utilizes reactive request handling with an event loop, and Kotlin coroutines with their suspend functions have become increasingly favored.

Tuning EMQX To Scale to One Million Concurrent Connection on Kubernetes

Aggregated on: 2023-06-06 17:15:46

When building an IoT-based service, we need to implement a messaging mechanism that transmits data collected by the IoT devices to a hub or a server. That mechanism is known as a messaging protocol. A messaging protocol is a set of rules and formats that are agreed upon among entities that want to communicate with each other. When dealing with IoT, one of the first things that come to mind is the limited processing, networking, and storage capabilities these devices operate with. These constraints make it challenging to implement a messaging protocol to facilitate communication. Ideally, we should use a protocol that takes all these issues into consideration.

From CPU to Memory: Techniques for Tracking Resource Consumption Over Time

Aggregated on: 2023-06-06 16:30:46

Sometimes, it is necessary to examine the behavior of a system to determine which process has utilized its resources, such as memory or CPU time. These resources are often scarce and may not be easily replenished, making it important for the system to record its status in a file. By doing so, it becomes feasible to identify the most resource-intensive process in the past. If the system has not encountered an Out-of-Memory (OOM) killer, which can be found in the syslog, this information can be used to further pinpoint the problematic process. Atop Tool: An Overview There is a special tool that can be used both for real-time monitoring system usage and collecting system status into logs in the background. This is atop. With atop, you can gather information on CPU and memory usage, which can also be collected by other popular monitoring tools like top and htop. Additionally, atop provides insights into I/O and network usage, eliminating the need to install additional tools for network and I/O monitoring, such as iftop and iostat. In my opinion, atop is a versatile tool for many tasks.

Agile Development Best Practices for Determining What To Automate

Aggregated on: 2023-06-06 13:30:46

Agile teams will not prosper if they don’t use frameworks to automate various development processes, including tests, builds, test environments, etc. Understanding that the primary goal of all agile teams is to successfully deliver real value to the customer, which can be interpreted as providing functional software after the sprint, is necessary to comprehend why a lack of automation results in failure. This article will address the central questions of “What can and what we shouldn’t automate in agile projects.” What Can We Automate in an Agile Environment? Most types of testing benefit from automation, starting from basic unit tests through system tests. But, as you know, unit tests don’t supply enough coverage to catch system regression failures. Running a set of manual tests before every check-in, which could be dozens of times a day, isn’t practical. When developers can’t run tests by pushing a button, they will not be motivated.

DevOps in Legacy Systems

Aggregated on: 2023-06-06 00:15:46

I had a discussion with one of my then-manager-colleagues about ensuring the movement of a planned item even if the only available team member has no expertise to take it on. The simple answer is to get that team member to a starting point with the help of the experienced ones, through a non-heavy pair work format, just enough to give them momentum. It is possible that the task won't be completed on time, but at least they got it moving. In practice, this is always easier said than done, since we always fall to the mindset of either: "It is going to be faster if the expert will do it" or "I'll just take this non-priority item which I have expertise on rather than mess up that very critical one." This somewhat siloed mentality is especially prevalent in legacy systems, adding to the hurdles of an already challenging DevOps adoption.

How to Use an Anti-Corruption Layer Pattern for Improved Microservices Communication

Aggregated on: 2023-06-05 22:30:46

What Is an Anti-Corruption Layer (ACL)? In the world of microservices architecture, communication between services is of utmost importance. However, with the increasing complexity of microservices, communication between them can become a challenge. That's where the Anti-Corruption Layer (ACL) pattern comes into play. This pattern is designed to improve communication between microservices by establishing a layer between them that acts as a translator, ensuring that services can communicate with each other seamlessly. The Anti-Corruption Layer pattern is based on the concept of Domain-Driven Design (DDD). It essentially creates a layer between two services that translates one service's language or communication protocol to the other service's language or communication protocol. This layer acts as a mediator, ensuring that the communication between the two services is smooth and efficient.

New ORM Framework for Kotlin

Aggregated on: 2023-06-05 19:30:46

If you have an aversion to new frameworks, don't even read this. For other kind readers, please note that here I'm going to present a proposal for an API for modeling database queries in a declarative style with strong Kotlin type checking primarily. Only some classes around entities are implemented; the database connection is missing for now. In the project, I tried to evaluate my experience and vision so far. However, not all ideas presented in this paper are completely new. Some of them I drew from the Ujorm framework, and the entity concept was inspired by the Ktorm framework. But the code is new. The prototype results from a mosaic that has been slowly pieced together and has now taken a form that is hopefully worth presenting. If you are not discouraged by the introduction, I will skip the general talk about ORM and let you get to the code samples. The demonstration examples use two relational database tables. This is an employee/department (unspecified organization) relationship where each employee may (or may not) have a supervisor. Both tables are described by entities from the following class diagram:

Dependency Injection (DI) is widely used to manage class dependencies and avoid issues that can arise from implicit dependency usage. Most modern frameworks have native support for the DI feature or can use third-party libraries for it. In this article, we will describe the implementation of DI in the Symfony framework. Symfony uses the PSR-11 compatible service container to store and obtain services. The service container is aware of all registered services and their dependencies and can provide an already initialized and properly created instance of the required service.

Event-Driven Architecture Using Serverless Technologies

Aggregated on: 2023-06-05 17:30:46

In modern architecture, most of the system has some component of Asynchronous computing. Any application which you see has one versus other Asynchronous communications. Popular Examples of such applications are Video Streaming Services, where you stream the packet of data and then render it on client applications, Popular messaging applications, or any of the collaboration tools. These are just a handful of examples, but you can think of asynchronous communication anywhere where you are not transiting the data in the same request/response. What Is Event-Driven Architecture? Event-driven architecture can be visualized as a bunch of the applications module triggered by some kind of event, and then it processes and puts these events back into some place to be consumed by the other application.

Mastering Go-Templates in Ansible With Jinja2

Aggregated on: 2023-06-05 17:00:45

The Power of Ansible, Jinja2, and Go-Templates in Streamlining DevOps Workflow Streamlining DevOps workflows with Go service templates can be an intimidating task, especially when dealing with YAML files that contain Go-inspired string interpolation, as seen in tools like Prometheus, Loki, and Promtail. However, when these files are managed with Ansible, a versatile IT automation tool, and Jinja2, a powerful Python templating engine, these complex tasks can be made easier and more efficient for DevOps professionals. The Challenge: Distinguishing Between Ansible Variables and Go Template Expressions A common challenge when using Ansible is distinguishing between Ansible variables and Go template expressions within YAML files. It's critical to generate a YAML file that includes literal {{ mustaches }} that Ansible should not interpolate. This is where Jinja2's {% raw %}{% endraw %} tags come into play, telling Ansible not to treat the enclosed text as Jinja2 code, thus avoiding variable interpolation.

Scalability and Extensibility: FastAPI's asynchronous architecture enables horizontal scaling, allowing banking APIs to handle a large volume of concurrent requests. Financial institutions can easily scale their API infrastructure based on user demand without sacrificing performance. Additionally, FastAPI's modular design and compatibility with other Python libraries provide developers with the flexibility to extend functionality by integrating with existing banking systems, databases, or third-party services. Automated Testing and Debugging: FastAPI encourages and facilitates automated testing with tools like pytest and pytest-bdd. These testing frameworks enable developers to write comprehensive tests, ensuring the correctness and stability of the API. FastAPI's integration with the Swagger UI and ReDoc documentation tools further simplifies testing and debugging by providing an interactive interface to explore and validate API endpoints. Here's an example of a parameterized FastAPI code that creates a banking REST API to connect to a SQL Server database, extract account summary and user details, and return the JSON response. The parameter values are passed using a separate configuration file. Let's go step by step.

Sometimes you need to control access to the data in your databases in a very granular way - much more granular than most databases allow. For instance, you might want some database users to be able to read only the last few digits of some credit card number, or you may need certain columns of certain rows to be readable by certain users only. Or maybe you need to hide some rows from some users under specific circumstances.

Aggregated on: 2023-06-05 17:00:45

Recently, we released the beta version of our platform for crypto traders, which allows real-time analysis of the growth and decline charts of most cryptocurrencies as well as historical data. Currently, the product is undergoing closed testing with a group of investors. We are receiving feedback on the quality of the platform, fixing any bugs that arise, and preparing for the next stage of developing a full-fledged version of the product. During the initial discussions with the client, we discussed the prospects of launching the project within 3-3.5 months, taking into account the scope of work, and assessed it as unlikely (50% probability of launching a "working" product) and high-risk (90% probability of failure). If you're interested, I can talk about the method of risk assessment in future articles. Here's why we came to this conclusion:

Part 1 can be found here. Lexer The Lexer serves as the most basic element. Its primary function involves iterating through the characters present in the source code. It may combine certain characters to create a single token and subsequently generate a token object with its associated type. This object is then added to the resulting list.

Understanding Dependencies...Visually!

Aggregated on: 2023-06-05 14:45:45

Show of hands, how many of us truly understand how your build automation tool builds its dependency tree? Now, lower your hand if you understand because you work on building automation tools. Thought so! One frustrating responsibility of software engineers is understanding your project's dependencies: what transitive dependencies were brought in and by whom; why v1.3.1 is used when v1.2.10 was declared; what resulted when the transitive dependencies changed; how did multiple versions of the same artifact occur?

Strategies for Reducing Total Cost of Ownership (TCO) For Integration Solutions

Aggregated on: 2023-06-05 14:15:45

Integration solutions play a vital role in connecting systems, applications, and data across an organization. While implementing these solutions is essential, it's equally important to minimize the Total Cost of Ownership (TCO) associated with their development, operation, and maintenance. By adopting cost-effective strategies, organizations can optimize their investments and achieve greater value from their integration initiatives. In this article, we explore effective approaches to reduce TCO for integration solutions. 1. Define Clear Objectives and Requirements Before embarking on an integration project, it is crucial to define clear objectives and requirements. This step ensures that the solution aligns with the strategic goals of the organization and helps avoid unnecessary development and maintenance costs caused by scope creep. By establishing well-defined objectives and requirements from the outset, you can maintain focus throughout the project, optimize resource allocation, and minimize the risk of unexpected expenses and delays.
