Complete Guide to Configuring SSH in Ubuntu

Comparing the Relational Database Management System to the Object-Relational Database Management System

A collection of services with great free tiers for developers on a budget.

So how do you use a database on a static file hoster? Firstly, SQLite (written in C) is compiled to WebAssembly. SQLite can be compiled with emscripten without any modifications, and the sql.js library is a thin JS wrapper around the wasm code

If you're here, you're likely concerned with making your user-facing products as delightful as possible. And error messaging plays an important role in that.

With the ease of deployment that SaaS services bring, most organizations are moving their infrastructure in the cloud. The ease of deployment can also lead to increasing costs if you do not plan ahead of time. Spinning up a new database for every new customer can easily be automated today, but down the line that would increase the hosting costs. At the same time, sharing customer data within a common database could result in leaking sensitive information across customers which could harm your re

Deploying applications to Kubernetes can sometimes feel cumbersome. You deploy some Pods, backed by a Deployment, with accessibility defined in a Service. All of these resources require YAML files for proper definition and configuration.

Helm packages are called charts, and they contain templates of resource definitions that deploy and configure given apps with minimal effort required from the user. With templating, you can manage the chart, its settings and behavior by passing in variable definitions without modifying the actual chart. Customized resource definitions, as well as modifications to already deployed definitions, Helm automatically manages. A deployed chart, with possible customizations, is called a release.

Kubernetes Ingresses allow you to flexibly route traffic from outside your Kubernetes cluster to Services inside of your cluster. This is accomplished using Ingress Resources, which define rules for routing HTTP and HTTPS traffic to Kubernetes Services, and Ingress Controllers, which implement the rules by load balancing traffic and routing it to the appropriate backend Services.

When deploying web apps to Kubernetes, you usually use Services and Ingresses to expose apps beyond the cluster at your desired domain. This involves manually configuring not only the Ingress, but also the DNS records at your provider, which can be a time-consuming and error-prone process. This can become an obstacle as your application grows in complexity; when the external IP changes, it is necessary to update the DNS records accordingly.
