If you want to deliver code more frequently and reliably, you’ve probably already heard about the benefit of CI/CD tools, used exactly for that purpose. The CI/CD Pipeline is one of the modern development practices related to DevOps services. Let’s explore together what it is, the difference between Continuous Integration and Continuous Development, and more importantly, the role of CI/CD for software development. What Does CI/CD Pipeline Stand For? Continuous integration and continuous delivery/continuous deployment are abbreviated as CI and CD, respectively. In a nutshell, CI/CD is a contemporary software development methodology wherein incremental code changes are done often and consistently. CI-triggered autonomous build-and-test stages guarantee that code changes submitted into the source are trustworthy.

Death to Tribal Knowledge

Aggregated on: 2022-01-04 15:49:31

Photo by Kelly Sikkema on Unsplash Documentation is a struggle for nearly every company. When information is undocumented, it remains as “tribal knowledge,” information that someone new to the company must ask others about in order to learn. This may work fine for a time, but what happens when those with the knowledge are unavailable? Or worse, what happens when those people leave the company? The knowledge leaves with them. Ridding your company of tribal knowledge is difficult in practice, but it can be done in three simple steps. First, document the information. Second, make sure people know where to find it. Third, make sure the documentation stays up to date.

Aggregated on: 2022-01-04 14:34:31

Over the years, the whole idea of software testing has evolved. And the evolution not only has called for modern testing strategies and tools but a detailed-oriented process with the inclusion of test methodologies. However, the only thing that defines the success or failure of a test strategy is the precise selection of tools, technology, and a suitable methodology to aid the entire QA process. This is why most newbies entering the industry tend to find automated functional testing a complex operation. As working on such an operation needs a precise system that can aid the ultimate goal of performance, functionality, and of course a pleasing user response.

Snowflake Data Processing With Snowpark DataFrames

Aggregated on: 2022-01-04 13:49:31

Introduction Snowpark is a new developer library in Snowflake that provides an API to process data using programming languages like Scala (and later on Java or Python), instead of SQL. The core concept in Snowpark is DataFrame that represents a set of data, e.g. a number of rows from a database table that can be processed using object oriented or functional programming techniques with our favorite tools. The notion of Snowpark DataFrames is similar to Apache Spark or Python Panda DataFrames. Developers can also create user-defined functions (UDFs) that are pushed down to the Snowflake server where they can operate on the data. The code execution is using lazy evaluation; this will reduce the amount of data to be exchanged between Snowflake warehouse and the client.

Micro-Frontend Architecture

Aggregated on: 2022-01-04 11:34:31

What Is a Micro-Frontend Architecture? The micro-frontend architecture is a type of design applied to the frontend that allows us to divide it into smaller, individual, and semi-independent applications that work together. This frontend concept is very much inspired by the microservices used mostly in the backend. The goal of this architecture is to see web applications as a composition of functionalities where each one is worked by independent teams. Each team has a specific business area and development is done end-to-end, from the database to the user interface.

Implementing Cloud Governance as a Code Using Cloud Custodian

Aggregated on: 2022-01-04 11:04:31

In today's scaling cloud infrastructure it's hard to manage all resources compliance. Every organization has a set of policies to follow for detecting violations and taking remediation actions on their cloud resources. This is generally done by writing multiple custom scripts and using some 3rd party tool and integration. Many development teams know how hard it is to manage and write custom scripts and keep a track of those. This is where we can leverage Cloud Custodian DSL policies to manage our Cloud resources with ease. What Is Cloud Governance? Cloud governance is a framework that defines how developers can create policies to control costs, minimize security risks, improve efficiency and accelerate deployment.

What Inspires the Product Owner in Software Development in 2022?

Aggregated on: 2022-01-04 10:34:31

The Product Owner is the person responsible for the development of the product, its "father," so to speak. Product Owner and Product Manager should not be confused — they are not equal positions. The Product Manager distributes the workload and tasks within the team, and is responsible for the management processes, while the Product Owner is responsible for the product itself. They see the end result and direct the team towards it. All stages of product creation are under the control of the PO.

Three easy ways to run Kafka without Zookeeper

Aggregated on: 2022-01-04 03:04:31

There has been a couple of years since the announcement of the removal of Apache Zookeeper as a dependency to manage Apache Kafka metadata. Since version 2.8, we now can run a Kafka cluster without Zookeeper. This article will go over three easy ways to get started with a single node cluster using containers. Control and data planes Apache Kafka implements independent control and data planes for its clusters. The control plane manages the cluster, keeps track of what brokers are alive, and takes action when the set changes. Meanwhile, the data plane consists of the features required to handle producers and consumers and their records. In the previous iterations, Zookeeper was the cluster component that held most of the implementation of the control plane.

The Role of AR/VR in Transforming the Manufacturing Industry Digitally

A Real-World Framework for Calculating Database Latency

Aggregated on: 2022-01-04 00:49:31

Almost all modern applications require storing and accessing data, but choosing the right database to power an application is a difficult task that involves reasoning about a complex set of tradeoffs. Developers typically need to think about the following: The geographic regions where the database will store data and whether the resulting real-world latency profile will allow them to create an application that is quick and responsive. The operational model for the database and the implied total cost of ownership and availability characteristics. The consistency model for the database and whether it meets requirements without pushing complex transaction support to the application. The developer experience for the database and whether it will empower fast and efficient innovation in the future. The scalability of the database and the ability to quickly dial capacity up or down as workloads change over time. These dimensions are all important, but latency stands apart from the rest because it is the most difficult to reason about and it is often impossible to engineer around. Low latency is also growing in importance as business logic moves to the edge, making the difference between a local and remote API call more jarring and disruptive to users.

How to Generate Customer Success Analytics in Snowflake

Aggregated on: 2022-01-03 23:49:31

As the distinction between data professionals and non-data professionals becomes smaller and smaller, the need for technology that bridges the gap between the two parties is crucial. The benefits of interacting with a data warehouse, especially with large amounts of data, are unquestionable, but as a peripheral member of the core technology team who might not be very technical, it is not always practical to generate SQL queries on the fly. This poses a problem, especially when departments such as sales, customer success, account management, etc., want the robust insights that could come from the vast amount of data that a company is storing, but they don’t necessarily know how to quickly gather these insights.

How To Utilize NoSQL DB: Graph Database Examples

Aggregated on: 2022-01-03 23:49:31

Since NoSQL Databases are widely used and preferred among developers, because of their close relation to the Agile methodology, we decided to focus on their functionality in this article. At first, we need to define how we see NoSQL abbreviation, considering that there are several different versions for that. In the battle of the meanings, we have literally the database without SQL usage, and "not only SQL." Surely, we’d prefer to cognize the second option, but not anti-definition, given that SQL is running in any backend and traditionally is not eliminated. The NoSQL databases create more intuitive methods of storing data, allowing to model the structured linkage that will be closer to the application’s form. They require fewer transformations when saving or retrieving with NoSQL APIs. Furthermore, NoSQL databases can fully utilize the Cloud to ensure minimal outage. As you can notice, NoSQL DB seems to be beneficial and more flexible than traditional storing. Let’s discover this difference in further detail.

Why Assessing Security Risk in Compute Lifecycle Development Should Be a Community Effort

Aggregated on: 2022-01-03 23:49:31

Supply chain risks continue to be a major concern for manufacturers, and the organizations and customers they serve. According to recent research, software supply chain attacks are up 650 percent in the past year alone and ENISA expects these types of attacks to quadruple by the end of 2021. But assessing supply chain risks can be a complex task for product teams. And when not done properly, can have devastating impacts. Just look at the SolarWinds attack and the recent blog from Microsoft showing that the group behind that attack, Nobelium, has since targeted 140 additional resellers and service providers.

Why PSP22 Is Important to The Polkadot Ecosystem

Aggregated on: 2022-01-03 23:49:31

Standards are critical to the successful development of emerging technologies, and Polkadot is no exception. It's important because the proper standard set at the right time can help improve interoperability and build trust within the technology ecosystem (opening the doors to mass adoption). Benchmarks like these are crucial to enable token-based smart contracts that interact with each other. Without a standard, anyone can develop and deploy their own smart contract. The problem with this approach is that they would have to expose the same function signature to enable true interoperability.

The Importance of Access Logs in Performance Issue Analysis

Aggregated on: 2022-01-03 23:04:31

An access log is generated by the web server to log the details about the request that it has processed. It logs status code, response time, URL, protocol, size, client IP address, etc., about the request. Load Balancers will have similar log files created to log the request details. While doing any performance analysis, these logs play an important role. It is being neglected most of the time due to lack of awareness and the usage of APM tools abstracts it from the users by allowing them to focus visually on coarse-grained data instead of fine-grained data. Most people are aware of the application server log but many of them are not aware of the web server/load balancer access log. Most of the time, this log will not be striking in the mind of a person who investigates the problem. Access logs are available for the below servers while the format for each of them varies:

Extracting Data From Very Large XML Files With X-definition

Aggregated on: 2022-01-03 17:04:31

X-definition is an open-source Java API that can be used to extract data from XML files regardless of their size. It will not compel the Java Virtual Machine to complain that it is out of heap memory, nor does it even require that your Java code step through the parts of your XML in the order of their occurrence until the location of the data you need is reached. It requires little more than a markup model of your XML document, and about 90 to 120 seconds of processing time for each gigabyte of XML data. In this article, we'll download a modest (2.5 GB) file from data.discogs.com and extract data from it using a minimum of code. Our X-definition instructions will amount to the following:

Create Lambda Layers in AWS Lambda

Aggregated on: 2022-01-03 16:04:31

For a while, I struggled when it came to making layers for my functions. I used to download them locally, zip them, upload them into S3 when their sizes were big, and then create a version. This process takes a long time, and chances are high that you will make a defective layer when you’re using Windows or Mac because of some layers that compile binaries when you download them. I wrote an article back in 2019 on how to do that with the help of Docker, and it still gets read, which triggers the need to create a new, simple, and extremely fast way to use this amazing feature: Lambda Layers.

How to Do UUID as Primary Keys the Right Way

Aggregated on: 2022-01-03 15:34:31

Why Do We Need Technical IDs in the First Place? Any properly designed relational database table owns a Primary Key (PK) allowing you to uniquely and stably identify each record. Even if the primary key can be composite (built of several columns), it is a widespread good practice to dedicate a special column (often named id or id_<table name>) to this end. This special column is used to technically identify records and can be used as foreign keys in relations. NOTE: Do not confuse technical (also named "surrogate") keys with function keys. The most important tables (so-called entities in domain-driven design) may contain an alternate human-readable ID column (like the customer ID "G2F6D"). In this article, we will focus only on technical PKs. They should only be processed and readable by machines, not humans.

Deploy an Application for Azure Container Registry

Aggregated on: 2022-01-03 13:04:31

Overview Docker Container and Image Introduction to Docker Images Docker is a tool that makes it easier to create, deploy, and run applications by using a containerization approach. These containers are lightweight and take less time to start than traditional servers. These containers also increase performance and lower cost, while offering proper resource management. Another benefit to using Docker is that you no longer need to pre-allocate RAM to each container. Docker Container and Docker Image A Docker container is a virtualized runtime environment used in application development. As mentioned before in the definition of Docker, with Docker, we are able to create, run and deploy applications that are isolated from the underlying hardware. A Docker container can use just one machine, share its kernel and virtualize the OS to run more isolated processes. So, Docker containers are lightweight. A Docker image is like a snapshot in other types of VM environments. It is a record of a Docker container at a specific point in time. Docker images are also immutable. While they can’t be changed, they can be duplicated, shared, or deleted. The feature is useful for testing new software or configurations because whatever happens, the image remains unchanged.

Raising the Bar on Security by Purging Credentials From the Cloud

Aggregated on: 2022-01-02 01:34:30

The Cloud is ubiquitous: any company looking to ramp up quickly will provision its compute, networking, and storage with its preferred cloud provider, and get started rolling out their products. That makes total sense from a business perspective. The Cloud has simplified development and automation exponentially over the years, and emerging tech such as AI and IoT will only accelerate this. However, the catch is that the very same foundational architectures which drive the Cloud’s efficiency, flexibility, and cost benefits ultimately also are its weakest links from a security perspective. The result is the daily march of headlines we all read about: ever larger and deeper breaches of data and systems.

Creating 5,000 background threads in my ASP.NET Web app

Aggregated on: 2022-01-01 13:49:30

I once saw a guy speaking about multi threaded programming, and he asked his audience how many of the people amongst had audience had created multiple threads, at which point half the room lifted their arms. Then he asked how many had used dozens of threads running simultaneously, at which point 25% of the room kept their arms up. When he reached the question "how many have created millions of concurrently executed threads" the speaker was the only person left with his arm raised. The reasons for this of course, is because the idea of creating millions of concurrently executed background threads is simply ridiculous to even imagine. However with Hyperlambda, at least in theory, this is actually quite easily achieved. To understand how this is possible, realise that multi threading is just a state machine, allowing you to perform context switches, at the CPU level, with an interrupt scheduling work for each individual thread.
