A Docker image is a combination of instructions and for creating a docker container a instruction is used to execute code in a Docker container. Docker images work as a set of instructions to build and run a Docker container, as a template. Docker images also perform as the initial point when using Docker. A Docker image contains read-only files. when a docker image is created it can not be changed and modified, insert template that has instructions for deploying containers.

Even before the cloud, no one liked deployment downtime. With applications hosted in traditional data centers that restricted access for local users, many organizations scheduled deployments when users were less likely to be using the applications, like the middle of the night. With widespread adoption of cloud-based, 24x7 environments available from all time zones, every hour of the day, easy-to-find deployment windows are gone.

At incident.io, we’re building tools to help people respond to incidents, often by automating their organisations’ process. Much of this is powered by our Workflows product, which customers can use to achieve things like: Workflows as a product feature are incredibly powerful, and we’re proud of the value they provide to our customers. Behind-the-scenes, though, building something like workflows can be difficult.

This is the second in a two part series on how we built our workflow engine, and continues from Building workflows (part 1). Having covered core workflow concepts and a deep-dive into the Workflow Builder in part one, this post describes the workflow executor, and concludes the series with an evaluation of the project against our goals.

You are not the only one asking this seemingly popular question! Several companies are torn between the rise in appeal of open-source databases and the undeniable challenges inherent to their adoption. Let’s explore the trends, the drivers and the challenges related to open-source database adoption.

When you’re investing in automation solutions, ultimately, tangible results need to follow quickly. Getting a return on investment (ROI) out of an automation project after two years is something that would have been OK in the not-so-distant past but is no longer acceptable nowadays. With the current speed of change, where new technologies come and go and existing ones evolve at lightning speed, IT teams require much faster time to value on automation investments.

Over the years we’ve received requests from our customers for a feature that can enable their customers and their end users to create/ report incidents directly on Squadcast. To our valued customers - we heard you! We are excited to introduce Webforms to do exactly that. In the past, we’ve addressed the challenges pertaining to On-call processes and best practices that teams can implement.

Welcome to episode 4 of our webinar series, From Theory to Practice. Blameless’s Matt Davis and Kurt Andersen were joined by Joanna Mazgaj, Director of Production Support at Tala, and Laura Nolan, Principal Software Engineer at Stanza Systems. They tackled a tricky and often overlooked aspect of incident management: problem detection. ‍

In this article, you’ll be introduced to two tools: Speedscale and NeoLoad. Both of these tools offer you a way to load test your applications. This post will compare their ease of setup, development experience, fit within a modern infrastructure, and integration into CI/CD. Load testing is not a new concept in any way: the term was common even before Google Trends started recording data in 2004.
