Redis and Memcached are both open-source, in-memory key-value data stores used for caching, but they differ in features and use cases. Redis stores data in memory and can persist to disk, supports data types beyond strings like lists and sets, and allows replication. Memcached only stores data in memory and does not support persistence or replication. While both are fast, Redis is more full-featured but requires more memory, making Memcached better for simple caching use cases with high traffic.

Introduction to Docker storage, volume and imageejlp12
Docker storage drivers allow images and containers to be stored in different ways by implementing a pluggable storage driver interface. Common storage drivers include overlay2, aufs, devicemapper, and vfs. Images are composed of read-only layers stacked on top of each other, with containers adding a writable layer. Storage can be persisted using volumes, bind mounts, or tmpfs mounts. Strategies for managing persistent container data include host-based storage, volume plugins, and container storage platforms.
This document provides an introduction to Docker including Docker vocabulary, architecture, file systems, networking, volumes, registry services like Docker Hub, and clustering technologies like Docker Swarm, Kubernetes and Mesos. It also covers setting up a local Docker environment, building Docker images with Dockerfiles, running containers, and deploying containers on AWS EC2 Container Service.
This document provides an overview of VMware vSphere solutions and how they compare to traditional server architectures. It shows how vSphere allows servers to run as virtual machines on shared storage, improving flexibility, redundancy, and disaster recovery. Diagrams depict how a vSphere implementation would integrate various applications like Sage 100 and EDI across virtualized servers, with an operating server managing the environment and a shared storage solution providing failover protection.
Docker allows you to package applications with their dependencies into standardized units called containers that can run on any Linux server. Containers are more portable and efficient than virtual machines, starting in milliseconds and using less disk space. Docker makes it easy to deploy and run applications without having to rebuild environments and guarantees that an application will run the same regardless of the infrastructure it is running on.

DAIS19: On the Performance of ARM TrustZoneLEGATO project
Presented by Valerio Schiavoni @vschiavoni at DAIS 19
The TrustZone technology, available in the vast majority of recent Arm processors, allows the execution of code inside a so-called secure world. It effectively provides hardware-isolated areas of the processor for sensitive data and code, i.e., a trusted execution environment (TEE). The Op-Tee framework provides a collection of toolchain, opensource libraries and secure kernel specifically geared to develop applications for TrustZone. This paper presents an in-depth performance- and energy-wise study of TrustZone using the Op-Tee framework, including secure storage and the cost of switching between secure and unsecure worlds, using emulated and hardware measurements.
Resilient microservices with Kubernetes - Mete Atamel - Codemotion Rome 2017Codemotion
Creating a single microservice is a well-understood problem. Creating a cluster of load-balanced microservices that are resilient and self-healing is not so easy. Managing that cluster with rollouts and rollbacks, scaling individual services on demand, securely sharing secrets and configuration among services is even harder. Kubernetes, an open source container management system, can help with this. In this talk, we will learn what makes Kubernetes a great system for automating deployment, operations, and scaling of containerized applications.
Get hands-on with security features and best practices to protect your containerized services. Learn to push and verify signed images with Docker Content Trust, and collaborate with delegation roles. Intermediate to advanced level Docker experience recommended, participants will be building and pushing with Docker during the workshop.

1. Docker is a container platform that packages applications and dependencies to run seamlessly in any computing environment. It helps eliminate issues caused by differences in computing environments.
2. Kitematic provides a graphical user interface for Docker that makes it easy to run Docker containers without using the command line. It allows visually managing containers.
3. The Docker CLI can be used to run containers by pulling images from Docker Hub, a registry for Docker images, and using commands like docker run to launch containers from those images.
Dockerizing Symfony2 application. Why Docker is so cool And what is Docker? And what are Containers? How they works? What are the ecosystem of Docker? And how to dockerize your web application (can be based on Symfony2 framework)?
The document provides instructions for installing Docker and Rally on Ubuntu Trusty 14.04. It includes adding Docker repositories, installing Docker, verifying the Docker installation, installing Rally within a Docker container, and setting up a Rally directory. Proxy configuration steps are also outlined for accessing repositories through a proxy server.
This document discusses deploying Django apps using Docker. Docker allows encapsulating apps from the host system in "containers" to make deployment repeatable without interfering with other host configurations. Key Docker terms include Dockerfile (commands to build images), images (snapshots of lightweight VMs), and containers (running instances of images). The document provides commands for building/running images and entering containers. It recommends getting a cheap VM from Digital Ocean with Docker preinstalled to easily test and use Docker.
Docker is not just about deploying containers to hundreds of servers. Developers need tools that help with day-to-day tasks and to do their job more effectively. Docker is a great addition to most workflows, from starting projects to writing utilities to make development less repetitive. Docker can help take care of many problems developers face during development such as “it works on my machine” as well as keeping tooling consistent between all of the people working on a project. See how easy it is to take an existing development setup and application and move it over to Docker, no matter your operating system.
Developing and Deploying PHP with DockerPatrick Mizer
The document discusses using Docker for developing and deploying PHP applications. It begins with an introduction to Docker, explaining that Docker allows applications to be assembled from components and eliminates friction between development, testing and production environments. It then covers some key Docker concepts like containers, images and the Docker daemon. The document demonstrates building a simple PHP application as a Docker container, including creating a Dockerfile and building/running the container. It also discusses some benefits of Docker like portability, separation of concerns between developers and DevOps, and immutable build artifacts.
This document discusses using Jenkins and Docker together for continuous integration and continuous delivery (CI/CD) pipelines. It describes how Jenkins can run as Docker containers, build and test Docker images, and integrate with Docker Hub for notifications. Specifically, it outlines how to 1) run Jenkins masters and slaves as Docker containers and 2) build, test, and deploy Docker images from Jenkins pipelines while tracing images back to their source code using fingerprints.
This document provides an overview of Docker and instructions for installing and using Docker. It discusses what Docker is, the main Docker tools, how to install Docker on different operating systems, and common Docker commands for pulling images, running containers, linking containers, building images with Dockerfiles, and more. The goal is to teach the reader how to containerize a web application using Docker.

LNUG: Having Your Node.js Cake and Eating It TooRob Tweed
The document discusses using Node.js for server-side applications. It introduces QEWD, a Node.js platform that allows running code in isolated worker processes to avoid Node.js's concurrency issues. QEWD uses a master process to queue incoming requests and dispatch them to separate worker processes. This allows Node.js code to leverage synchronous logic and avoid CPU-intensive tasks blocking other requests. The document argues this allows developers to "have their Node.js cake and eat it" by using Node.js for all application needs.
EWD 3 Training Course Part 45: Using QEWD's Advanced MicroService FunctionalityRob Tweed
This document discusses advanced microservice functionality in QEWD, including templated routes, dynamic path-defined destinations, federated composite microservices, redirection of responses, and chained microservices. It provides an example of extending a previous login microservice example to demonstrate these features. Templated routes allow variable path components that are passed to handler functions. Security is improved by adding authentication against JSON web tokens in the beforeMicroserviceHandler function.

EWD 3 Training Course Part 36: Accessing REST and Web Services from a QEWD ap...Rob Tweed
This document describes how to create a REST proxy using QEWD. It involves:
1. Amending the backend restDemo.js module to extract the REST call logic into a separate function and define a 'proxy' handler function.
2. Setting the module to be a REST module.
3. Having the proxy handler function invoke the extracted REST call logic to proxy requests to the actual REST service.
4. Adding a route in the QEWD startup file to route the /api/proxy URL to the proxy handler function, exposing the REST service via the proxy.
This allows the module to act as a REST proxy to the external JSONPlaceholder service while still supporting normal interactive apps
