This document discusses principles of Continuous Delivery and DevOps. It defines key terms like Continuous Integration, Continuous Delivery, and DevOps. The document explains that the goal of Continuous Delivery is to have working software in production. It outlines ingredients for Continuous Delivery like culture, automation, and testing. It also discusses patterns and anti-patterns and provides guidance on getting started with Continuous Delivery.
The Wall Street Journal already mentioned it in 2011: “Software is eating the world”. The world is starting to discover that nowadays, every company is an IT company. Product owners and other business representatives are seeing their competitors release new features to end users every day, and are demanding the same from their own software teams.
How do you measure up to this heavy pressure as an IT organisation? How to you manage to be able to quickly make changes to software systems in fast paced environments, without losing grip on quality? How do you build and test software in such a way, that it's always in a releasable state?
In this talk, I'll explain the principles of Continuous Delivery. You'll leave the session with enough insights to get started yourself right away.

DevOps on AWS: Deep Dive on Continuous Delivery and the AWS Developer ToolsAmazon Web Services
Today’s cutting-edge companies have software release cycles measured in days instead of months. This agility is enabled by the DevOps practice of continuous delivery, which automates building, testing, and deploying all code changes. This automation helps you catch bugs sooner and accelerates developer productivity. In this session, we’ll share the processes that Amazon’s engineers use to practice DevOps and discuss how you can bring these processes to your company by using a new set of AWS tools (AWS CodePipeline and AWS CodeDeploy). These services were inspired by Amazon's own internal developer tools and DevOps culture.

Building and Scaling High Performing Technology Organizations by Jez Humble a...Agile India
High performing organizations don't trade off quality, throughput, and reliability: they work to improve all of these and use their software delivery capability to drive organizational performance. In this talk, Jez presents the results from DevOps Research and Assessment's five-year research program, including how continuous delivery and good architecture produce higher software delivery performance, and how to measure culture and its impact on IT and organizational culture. They explain the importance of knowing how (and what) to measure so you focus on what’s important and communicate progress to peers, leaders, and stakeholders. Great outcomes don’t realize themselves, after all, and having the right metrics gives us the data we need to keep getting better at building, delivering, and operating software systems.

The process of building and deploying software can be tedious, difficult, and problem-prone. Even more challenging is building a continuous integration and delivery platform that can be flexible and adaptive to your agile software teams. Take a sneak peek into how Dude Solutions revamped and replaced their entire continuous integration and delivery process with a brand new environment and toolset in just under 3 months! We will share our experiences: the good, the bad, and the ugly.
[WSO2Con EU 2017] Continuous Integration, Delivery and Deployment: Accelerate...WSO2
Continuous integration, continuous delivery, and continuous deployment are essential practices adopted by agile organizations to meet the new demands of digital transformation. Ultimately, the goal is to accelerate development and test processes and get new code out to production fast. This slide deck focuses on sustainably flowing ideas into the hands of customers in the form of innovative digital capabilities and applications, and continuously improving the digital business with CI/CD.
Measure and Accelerate Your Software DeliveryAnand Chauhan
Many companies adopt the DevOps practices, but struggle to realize the impact the DevOps investment is making to improve software delivery. Disconnected teams, tools and increasing complexity leads to no visibility into how and where to optimize the process, deliver value to customers and maximize return on that investment. The session covers industry trends, critical need for measurement and touches on CloudBees DevOptics solution purpose built to provide immediate transparency you need to measure, optimize and improve your software delivery process.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

29. “Continuous Delivery won’t work here”
• Stated reasons:
• we’re regulated
• we’re not building
websites
• too much legacy
• our people are too
stupid
• Actual reasons:
• our culture stinks
• our architecture
