Migrating Monoliths to Microservices in Practice

Aggregated on: 2022-08-30 19:23:03

There have been amazing articles on the subjects of migrating from a monolith to a microservice architecture, e.g., this is probably one of the better examples. The benefits and drawbacks of the architecture should be pretty straightforward. I want to talk about something else, though: the strategy. We build monoliths since they are easier to get started with. Microservices usually rise out of necessity when our system is already in production. However, there are a lot of questions that arise when deciding when to do the migration or not – how do you decide the boundaries of a service? How do you verify the self-healing properties of your microservice architecture?

It's not so hard to create a single endpoint API or a "Hello, World!" page. But what about creating a complete microservice: multiple endpoints with CRUD services, business logic enforcement, and a multi-page application? Well, that's a horse of an entirely different feather. In this article, we'll show how to use open source technologies to:

What to Learn First: Docker or Kubernetes?

Aggregated on: 2022-08-30 17:23:03

When it comes to app development, many people wonder what to choose, Docker or Kubernetes. However, both technologies are vital to proper containerization. Accordingly, learning them at the same time can move you ahead of the competition and turn you into a demanded professional. When we speak of container technologies, both Docker and Kubernetes are open-source leaders. While many people are trying to figure out which one to learn first, they are basing their decision on a misconception.

Is IntelliJ Making Us Stupid? It's Complicated

Aggregated on: 2022-08-30 15:53:03

My last Java certification is the SCJP 6 from 2010, so when the OCP 17 came out, I thought it high time for a refresher. I am setting aside an hour every day when I’m at my brightest, which is after coffee and before breakfast. I'll share my personal study tips later, but it's more credible if I first pass the exam. So, I found another topic to distract me from my studies that I want to dwell on. It’s the effect that modern IDEs and resources like Stack Overflow are having on our brains. Once you dig into the 900+ pages of schoolwork that is the OCP Study Guide, you’re painfully reminded that they have been making us lazy and maybe even a bit stupid. Granted, the sheer number of facts to digest would have been less overwhelming if I had kept up more closely with the state of the art over the last decade. Several new features have been added, of whose existence I was at best only aware. After fifteen years of using Java, you tend to rely on tried and tested ways, for which there is no excuse of course. It’s a classic example of not sharpening the saw, so shame on me.

AWS Lambda Timeout and How to Overcome It

Aggregated on: 2022-08-30 15:23:03

It’s happened to the best of us. You’re in the middle of a task when all of a sudden, the inevitable lambda timeout occurs. Running into a timeout can feel like a bit of a setback when you’re trying to focus on running your application. At worst, timeouts can ultimately lead to a negative impact on the overall user experience, and a non-optimized application is bound to result in a loss of users, which can lead to financial repercussions.

Microservices In a microservice architecture, as a rule, authentication/authorization is a separate service.

How Does Routing Work?

Aggregated on: 2022-08-30 04:23:02

Purpose of Routing Routes are created to allow nodes to communicate data packets across networks. In order to route data packets to their destination, they travel along a series of links, each link having a single direction (one-way). A link is formed by joining two adjacent routers together; the router at either end of a link is called the ingress or egress router. The purpose of routing is to find the best path between two points. Routers exchange information about what routes exist between them using standard protocols. When a packet of data arrives at a router, the router will examine its header to determine where it should send the packet. If the router does not know how to reach the specified destination address, it sends the message to an adjacent router via a neighboring node. Each router stores a table of addresses it knows about. These tables are known as routing tables.

Using Machine Learning to Automate Kubernetes Optimization

Aggregated on: 2022-08-30 01:53:02

Note: This is the third article of a series covering Kubernetes resource management and optimization. In this article, we explain how machine learning can be used to manage Kubernetes resources efficiently. Previous articles explained Kubernetes resource types and requests and limits. As Kubernetes has become the de-facto standard for application container orchestration, it has also raised vital questions about optimization strategies and best practices. One of the reasons organizations adopt Kubernetes is to improve efficiency, even while scaling up and down to accommodate changing workloads; however, the same fine-grained control that makes Kubernetes so flexible also makes it challenging to effectively tune and optimize.

Commonly Occurring Errors in Microsoft Graph Integrations and How to Troubleshoot Them (Part 1)

Aggregated on: 2022-08-30 01:23:02

With the release of Exchange Server in 2007, Microsoft also introduced Exchange Web Services (EWS). These SOAP-based APIs allow developers to access Microsoft Exchange products such as calendars, contacts, etc. over the internet. As part of the Office 365 product launch, Microsoft also released the new REST-based Office 365 Unified APIs, later known as the MS Graph APIs, in 2015. Microsoft announced in 2018 that there would be no more active development for the EWS APIs. The Exchange Web Services no longer meet today's security and maintenance requirements. For this reason, the various EWS APIs will be gradually shut down from 2022 on and replaced by the MS Graph APIs. An overview of services already accessible via the MS Graph APIs can be found in the current documentation from Microsoft. Due to the switch to MS Graph, various companies have to adapt their digital products. In this article series, we will discuss some of the lessons learned during such a transition to Microsoft Graph REST API v1.0 with the MS Graph Java SDK.

Understanding Consistency Level in the Milvus Vector Database

Aggregated on: 2022-08-29 21:23:02

Have you ever wondered why sometimes the data you have deleted from the Milvus vector database still appear in the search results? A very likely reason is that you have not set the appropriate consistency level for your application. Consistency level in a distributed vector database is critical as it determines at which point a particular data write can be read by the system. Therefore, this article aims to demystify the concept of consistency and delve into the levels of consistency supported by the Milvus vector database. What Is Consistency?Before getting started, we need to first clarify the connotation of consistency in this article, as the word "consistency" is an overloaded term in the computing industry. Consistency in a distributed database specifically refers to the property that ensures every node or replica has the same view of data when writing or reading data at a given time. Therefore, here we are talking about consistency as in the CAP theorem. For serving massive online businesses in the modern world, multiple replicas are commonly adopted. For instance, online e-commerce giant Amazon replicates its orders or SKU data across multiple data centers, zones, or even countries to ensure high system availability in the event of a system crash or failure. This poses a challenge to the system - data consistency across multiple replicas. Without consistency, it is very likely that the deleted item in your Amazon cart reappears, causing a very bad user experience. Hence, we need different data consistency levels for different applications. And luckily, Milvus, a database for AI, offers flexibility in consistency level, and you can set the consistency level that best suits your application. Consistency in the Milvus Vector DatabaseThe concept of consistency level was first introduced with the release of Milvus 2.0. The 1.0 version of Milvus was not a distributed vector database, so we did not involve tunable levels of consistency then. Milvus 1.0 flushes data every second, meaning that new data are almost immediately visible upon their insertion and Milvus reads the most updated data view at the exact time point when a vector similarity search or query request comes. However, Milvus was refactored in its 2.0 version, and Milvus 2.0 is a distributed vector database based on a pub-sub mechanism. The PACELC theorem points out that a distributed system must trade off between consistency, availability, and latency. Furthermore, different levels of consistency serve different scenarios. Therefore, the concept of consistency was introduced in Milvus 2.0, and it supports tuning levels of consistency. Four Levels of Consistency in the Milvus Vector DatabaseMilvus supports four levels of consistency: strong, bounded staleness, session, and eventual. And a Milvus user can specify the consistency level when creating a collection or conducting a vector similarity search or query. This section will continue to explain how these four levels of consistency are different and which scenario they are best suited for. 1. StrongStrong is the highest and the most strict level of consistency. It ensures that users can read the latest version of data. An illustration of strong consistency.

A Comprehensive Agile Testing Methodology for Effective Software Development

Aggregated on: 2022-08-29 19:23:02

Software testing plays a crucial role in the agile software development environment. Agile testers act as a bridge between product owners/stakeholders and developers and thus work collaboratively. Through this, an ongoing feedback loop is formed, which improves the quality of a software product or application methodically and consistently. This article will teach you the strategic importance of agile testing methodology in a software development environment. What Is an Agile Testing Methodology? It is a software testing process that works on the principles laid down by agile software development. The iterative development methodology aligns with the agile testing methodology, where the customer requirements are focused on and worked accordingly. Agile testing methodologies adopt a continual approach. The testing is initiated in the initial stages of the project development. There is continual interaction between the product owner, developers, testers, and other key members to ensure a good quality software product or application is being built.

Prototype Pattern in JavaScript

Aggregated on: 2022-08-29 18:53:02

As a sound JavaScript developer, you must write clean, easy-to-understand, and maintain code. You solve exciting and unique problems that might not require unique solutions. You may have written code that resembles the solution to a complex problem you encountered before. Although you may not acknowledge it, you were using Design patterns. Design patterns refer to a general reusable and repeatable solution for a common set of problems while developing a software solution. Design patterns are not a finished project to be transformed directly into the source code. However, it is a template that helps developers understand the way to solve different problems with different solutions in multiple scenarios.

How We Built Our Documentation on Docusaurus

Aggregated on: 2022-08-29 18:53:02

It requires an ample amount of time, effort, and resources to produce great, user-friendly documentation. Good documentation is fundamental to the way engineers get started with a product and ultimately use it in the long run, which makes it essential to both user retention and growth. Building our documentation at Courier was a task we, therefore, took very seriously. We originally created our documentation for a very small, specific audience with specific uses for Courier. Over time, however, as our user base, their use cases, and our product itself has grown, we needed to improve and expand our documentation in order to cover our bases. This time, we wanted to make it scalable and focus on a great user experience. We decided to use Docusaurus to do so, which allowed our engineers to collaborate and update our documentation more efficiently. Here’s how we built our documentation and what we learned in the process that might be useful to you.

A Beginner’s Guide to Understanding Encryption Vs Decryption

Aggregated on: 2022-08-29 17:08:02

A computer system must promise or at least assure privacy and confidentiality when it transmits sensitive or personal data. A simple system, unless equipped with the proper technology, cannot stop any unauthorized access to cyber criminals. And in this computer era, data tampering needs no introduction as it is not something unheard of. So if you want to prevent or altogether stop the mishap, one of the best ways is to alter the data as it will prevent unauthorized access. The technique employed to alter the data is known as cryptography, and this process takes place in two phases- encryption and decryption of information. So if you want to find out what encryption vs. decryption is all about, keep reading:

What Is Encryption and How Does It Work?

Aggregated on: 2022-08-29 15:23:02

What Is Encryption? Encryption encodes data, so only programs that know how to decode it can read it. It uses an algorithm—a set of ordered steps—to alter the information so that the receiving party can't read it without applying a similar algorithm to return it to its original state. Encoding data is called encrypting. Decoding is called decrypting. The original unencrypted data is called plaintext, while we refer to the encrypted data as ciphertext. So, we encrypt plaintext into ciphertext and decrypt the ciphertext back into plaintext.

A Hybrid Approach to Continuous Application Authorization

Aggregated on: 2022-08-26 14:53:00

Applications need to maintain logged-in “sessions” for all users that use their app. Once a user logs in, they can continue to access parts of the application without having to log in (i.e., authenticate) again and again for each subsequent request made to the server. There are two main ways to do this: one is JSON Web Tokens (JWTs), and the other is session tokens. Both have pros and cons. Now, there’s a hybrid approach that takes advantage of the best of both. JWTs and Session Tokens: Pros and Cons With JWTs, the user data is stored client-side within the token itself. This makes JWTs a popular session management solution among developers looking to reduce their server load and improve latency. One downside is that session cancellation can be more difficult because the validation happens client-side rather than server-side. Due to the client-side validation, this can cause greater security concerns because you can’t easily revoke the underlying session if there’s a threat.

Our previous article introduced bytecode and discussed what it includes. This article will delve a bit deeper into ConstantPool. Highlights Bytecode is a representation that is abstract in nature. They are fictitious codes for a fictitious machine known as the Java virtual machine. The Java virtual machine is a piece of software that interprets bytecode. The JVM is a stack-based computer. Real CPUs are register-based systems and execute machine code. Java is compiled into bytecode, an intermediate form, which is then executed by the just-in-time (JIT) compiler, which generates machine code. Before going any further, let's explore javap, which is a very handy tool for deconstructing byte code.
