The 10-Minute Read to Understanding DevOps Tools: Update for 2023

Aggregated on: 2023-10-31 13:03:28

Hey everyone, this is by far my most read article, and given the changing landscape of DevOps tools, I thought nearly three years later and heading into 2023 it was worth a refresh! For those of you who read the original article, I have updated it with a few small changes to my categorization of tools list since last time and added new key players to most of those categories (along with a few I missed the first time). There are so many test tools across all the various tech stacks and DevOps stacks, that I can't possibly put them all in here, but this time I tried to add some tools used in different worlds (JavaScript, Kubernetes, Java, front end, etc). Before getting to the updated article, here is a summary of some key trends we have seen across our 30+ projects and from our friends at Rhythmic Technologies in the industry. We have seen an explosion of tools around microservices, particularly in the Kubernetes space. Tools like Envoy provide layer 7 proxy, and Istio and Linkerd provide layer 7 service mesh. At this point I consider these tools more purely operational tools, so I have excluded them from my list, but this may change on the next update! For well-run shops we have seen a lot of “less is more” lately. A lot of simpler pipelines, smaller test suites, less stages, less environments. A lot more Docker. Not necessarily a unified approach to Docker, but more of it! For mismanaged shops we have seen a significant growth of complexity, mostly around microservices; instead of DevOps being used to reduce and manage cloud spend, it seems to have the opposite effect in these shops. Simplified CI/CD approaches are on the rise, more GitHub actions and Bitbucket pipelines. Moving DevOps/IAC code into the repositories they support (yay!) Code coverage for infrastructure as code has gone up dramatically in the last 2 years. Low-level infrastructure (VPCs, related networking, security config, IAM) coverage remains low but it has improved a bunch. Last week a few of my very senior colleagues and myself were remarking about how many new DevOps tools are emerging and how it’s getting harder and harder every day to keep track of them and where they fit into the world. I asked several of them where these tools, Ansible, Terraform, Salt, Chef, Bamboo, CloudFormation, fit in. Why would I use one vs. the other? Are they even the same thing? Am I missing a major player? I got back the same blank stares/questions that I had. So, I thought I would do some research, read, and try to make sense of it for all of us so we could classify products into categories or uses to which we are all familiar.

Domain-Driven Design

Aggregated on: 2023-10-30 17:03:27

Building software that meets the needs and expectations of businesses and users in a dynamic and ever-changing technological world can be challenging. Software companies gradually require a workable way to make communication between the business and the product team more transparent. The domain-driven design (DDD) approach helps to solve this problem by fostering a profound understanding of the subject matter and continuous collaboration between developers and business experts. In fact, developers gain a more in-depth understanding of the underlying domain and business rules through constant communication. At the same time, stakeholders gain a better understanding of technical capabilities and constraints. For example, Standish Group’s analysis of 100 projects found that 70% of rework was due to a lack of domain knowledge during the requirements and design phases, confirming that DDD fosters understanding between businesses and developers.

Command Query Responsibility Segregation (CQRS)

Aggregated on: 2023-10-30 16:18:27

The Initial Need Leading to CQRS The traditional CRUD (Create, Read, Update, Delete) pattern has been a mainstay in system architectures for many years. In CRUD, reading and writing operations are usually handled by the same data model and often by the same database schema. While this approach is straightforward and intuitive, it becomes less effective as systems scale and as requirements become more complex. For instance, consider a large-scale e-commerce application with millions of users. This system may face conflicting demands: it needs to quickly read product details, reviews, and user profiles, but it also has to handle thousands of transactions, inventory updates, and order placements efficiently. As both reading and writing operations grow, using a single model for both can lead to bottlenecks, impacting performance and user experience.

A Study on Java Static Analysis Tool Reports Triage Using Machine Learning Approaches

Aggregated on: 2023-10-30 15:48:27

This study offers a thorough exploration of the effective triage of findings from Java static analysis tools utilizing cutting-edge machine learning techniques. Finding and prioritizing serious issues indicated by static analysis techniques gets more difficult as software projects become more complicated. By employing machine learning approaches to automate the report triage process, the proposed study seeks to address this problem. In this work, we first gather and preprocess a varied dataset of reports from several open-source Java static analysis tools. The dataset includes several types of code quality problems, including bugs, security flaws, and code smells. Then, in order to accurately portray the characteristics of each issue, we investigate and extract pertinent elements from the reports. We test a number of machine learning methods, including but not limited to decision trees, random forests, support vector machines, and neural networks, in order to accomplish the triage. We choose the most appropriate model for report categorization by a thorough comparison study that displays the best accuracy, precision, recall, and F1 score. Additionally, in order to enhance the overall performance of triage, we suggest a unique hybrid technique that incorporates the advantages of various machine learning models. The hybrid strategy makes use of ensemble techniques to tap into the combined wisdom of many classifiers, improving prediction skills. The success of the machine learning-based triage method is shown by our testing findings, which also show a considerable reduction in the time and manual labor needed to prioritize issues. The effectiveness of the triage approach enables software engineers to quickly resolve urgent concerns with the quality of their code, improving the dependability, maintainability, and security of their products. Introduction Static analysis of Java programs refers to the technique of looking at the program's source code without actually running it. It is a crucial step in the creation of contemporary software and is normally carried out using specialized tools. Static analysis's main objective is to spot any bugs, security holes, coding style infractions, and other problems early in the development process so that developers may fix them before the code is released[1]. Static analysis tools analyze the code without running it and can help to ensure code quality, improve maintainability, and increase overall software reliability. It's crucial to remember that while static analysis can identify a variety of problems, it cannot take the place of thorough testing, which includes user acceptability testing, unit testing, and integration testing. Static analysis combined with other testing techniques results in a more solid and dependable software development process[2]. Without running the code, static analysis techniques can assist in finding possible problems and vulnerabilities. By prioritizing and fixing significant issues more effectively, developers may increase the overall quality of their software by researching the efficacy of machine learning algorithms for triaging these reports. It might take a long time for developers to manually analyze each report that static analysis tools create since there are so many reports[3]. Automating the triage procedure may save time and money while freeing up engineers to concentrate on fixing pressing problems and boosting productivity. Java code mistakes, bugs, and security vulnerabilities may all be found using static analysis techniques. A more resilient and secure software system can result from effective triaging utilizing machine learning, which can ensure that the most serious and often recurring problems are handled first[4]. Technical debt, often known as a backlog of issues and unsatisfactory code, is a common problem in software projects[5]. Development teams may deliberately manage technical debt and minimize it by using machine learning to prioritize static analysis reports, improving long-term maintainability. False positives — problems that are reported as problems but aren't — can be produced by several static analysis technologies[6]. Developers may create models using machine learning that can discriminate between real problems and false positives, producing more accurate reports and avoiding wasting time on problems that don't exist. Researchers and developers can learn more about the weaknesses and benefits of the current static analysis tools by studying machine learning methods for report triage[7]. These tools may be improved and refined using the information provided to make them more useful and suited to certain use situations. Static analysis report triage using machine learning is a useful and difficult real-world application. Such methods may be investigated and developed to push the limits of machine learning methods, resulting in improvements in the area and perhaps even helping other fields. Examining how to use machine learning for triage Wide-ranging advantages of Java static analysis tool reports include increased software quality, resource effectiveness, bug fixes, technical debt management, and improvements in both static analysis tools and machine learning methods[8]. A crucial component of healthcare is triage, the practice of ranking patients according to the seriousness of their conditions. This is especially true in emergency and crisis circumstances where there are few resources. Triage systems' effectiveness and accuracy may be considerably increased with the use of machine learning techniques[9]. On the basis of numerous input characteristics, including vital signs, symptoms, medical history, etc., machine learning algorithms may be trained on past patient data to develop prediction models that assess the severity of a patient's illness. These models can aid medical personnel in swiftly determining which patients need urgent treatment. Free-text reports of patients' symptoms and complaints can be analyzed using NLP algorithms to provide structured data that can be utilized for triage[10]. This enables healthcare personnel to use unstructured data for triage choices, such as clinical notes and medical records. Machine learning may be used to find unusual and serious situations that standard triage techniques can overlook[11]. The system may identify outliers that need quick attention by inferring trends from past data. Based on their condition, proximity to the facility, and available resources, machine learning may be used to direct patients to the best healthcare institution[12]. During busy periods, this may aid in dividing the patient load among healthcare facilities fairly. Machine learning models may customize the triage decision based on the unique requirements of each patient by taking into consideration personal patient variables like age, medical history, and comorbidities [13]. It's crucial to remember that while machine learning techniques present intriguing triage solutions, they should never be utilized in place of the knowledge of healthcare professionals but rather as decision-support tools[14]. To guarantee patient safety and data security, the implementation of such technologies also requires thorough validation, ethical considerations, and adherence to privacy legislation[15].

10 Software Quality Factors That Should Always Be Remembered

Aggregated on: 2023-10-27 20:48:26

Flexibility and Extensibility Flexibility is the ability of software to add/modify/remove functionality without damaging the current system. Extensibility is the ability of software to add functionality without damaging system, so it may be thought of as a subset of flexibility. Those functionality changes may occur according to changing requirements, or an obligation if the development process is one of the iterative methods. Change is inevitable in software development and so, this is one of the most important properties of quality software Maintainability and Readability Maintainability is a little similar with flexibility but it focuses on modifications about error corrections and minor function modifications, not major functional extensibilities. It can be supported with useful interface definitions, documentation, and self-documenting code and/or code documentation. The more correct and useful documentation exists, the more maintainability can be performed.

Producing Messages at Warp Speed: Best Practices for Optimizing Your Producers

Aggregated on: 2023-10-26 18:03:25

Memphis.dev recently organized its first hackathon; participants were tasked with saving the island of Zakar by predicting wildfires from temperature sensor data and social media posts. To set up the hackathon, I simulated seven years of data, generating more than four million messages. Each participant needed to load that data into their Memphis Cloud account, so I wrote an upload script using the Python SDK. When I tested the script on my home network, I was easily seeing ingestion rates of 11,000 messages per second. But when I tested it using my Memphis Cloud account, messages were only being produced at a rate of 30 messages per second. Oh no! What gives?! And how did I end up fixing it?

Transaction Isolation Levels For The Highest Possible Performance

Aggregated on: 2023-10-26 17:03:25

It’s All About the Performance SQL database cannot handle only one incoming connection at a time because it would be devastating for the performance of the system. We expect the database to accept many callers in parallel and execute their requests as fast as possible. It is rather clear how to do that when these callers ask for different data, i.e., the first caller reads from Table 1 while the second caller reads from Table 2. However, very often, different callers want to read from and write to the same table. How should we handle these queries? What should be the order of operations and the final result? This is where a transaction isolation level comes into play. A transaction is a set of queries (like SELECT, INSERT, UPDATE, DELETE) sent to the database to execute, which should be completed as a unit of work. This means that they either need to be executed or none of them should be executed. It takes time to execute transactions. For instance, a single UPDATE statement may modify multiple rows. The database system needs to modify every row, and this takes time. While performing an update, another transaction may begin and try to read the rows that are currently being modified. The question we may ask here is — should the other transaction read new values of rows (despite not all of them being already updated), old values of rows (despite some of them being already updated), or maybe should it wait? And what if the first transaction needs to be canceled later for any reason? What should happen to the other transaction?

Zabbix as Universal Monitoring System for IT Company: Tips for Effective DevOps Monitoring

Aggregated on: 2023-10-26 16:48:25

Today, I want to share my experience working with Zabbix, its architecture, its pros, and its cons. Zabbix is a universal monitoring tool that combines data collection, data visualization, and problem notification. It also allows for some advanced features, such as problem prediction.My first encounter with this monitoring system was in 2014 when I joined a project where Zabbix was already in use for monitoring network devices (routers, switches). Back then, it was version 2.2, and it had a somewhat challenging web interface, even for that time. Over the course of five years, while working on the project, we went through several system upgrades until we finally transitioned to Zabbix 4.0 LTS. The number of monitored network devices grew to several hundred, and we added monitoring for VPN tunnels, physical servers, VMware vCenter, virtual machines, and some services like DNS and NTP. All of this required creating numerous XML templates, but it was worth it as Zabbix, together with the SIEM system, became the main tools for the OPS team.

Architecture Decision Records

Aggregated on: 2023-10-26 16:48:25

During project and product development, software engineering teams need to make architectural decisions to reach their goals. These decisions can be technical or process-related. Technical: Deciding to use JBOSS Data Grid as a caching solution vs Amazon Elasticache or deciding to use the AWS Network Load Balancer (NLB) vs AWS Application Load Balancer (ALB). Process: Deciding to use a Content Management portal for sharing documents or project-related artifacts. Making these decisions is a time-consuming and difficult process, and it's essential that teams justify, document, and communicate these decisions to relevant stakeholders.
