Is OpenStack Neutron production ready for large scale deployments?Елена Ежова
OpenStack Neutron with ML2 OVS has always been a challenging component in terms of performance and scalability. However, in recent releases, several enhancements and bug-fixes have resulted in significant improvements in overall reliability, performance and scalability of Neutron. In this presentation, we will share the results of our testing (both control-plane and data-plane) at large scale and provide a detailed data-driven analysis that explores the true scale limits and bottlenecks of Neutron.
This presentation was shown at the OpenStack Online Meetup session on August 28, 2014. It is an update to the 2013 sessions, and adds content on Services Plugin, Modular plugins, as well as an Outlook to some Juno features like DVR, HA and IPv6 Support
This is my latest OpenStack Networking presentation. I presented it at OSDC 2014. It includes a lot of backup slides with CLI outputs that show how ML2 with the OVS agent creates GRE based overlay networks and logical routers
This was a tutorial which Mark McClain and I led at ONUG, Spring 2015. It was well received and serves as a walk through of OpenStack Neutron and it's features and usage.

OOP paradigm, principles of good design and architecture of Java applicationsMikalai Alimenkou
Not so many developers are clearly make a distinction between design and architecture, and the experience of the interviews shows that the basic paradigm of OOP often cause difficulty. Java language is quite old and not all principles were implemented properly in it, and the abundance of frameworks further confuses developers. This presentation will discuss the basics of OOP and modern look on them, the benefits and harms of inheritance, interfaces, and the applicability of the opportunities that they offer for the ever-growing project. It will also consider the appearance of the normal cycle of code to work on TDD, how to postpone the architectural and design solutions until the right moment, tried and tested over the years architectural design patterns, principles of good code design. This talk will be useful to those who want to create high-quality, understandable and easy to support solutions in Java.

Architecting your WebRTC application for scalability
Arin Sime, CEO/Founder at WebRTC.ventures and AgilityFeat, & Alberto González Trastoy, CTO at WebRTC.ventures | Software/Telecom Engineer.
There are many ways to architecture your live video application with WebRTC. Open Source and CPaaS media servers are one consideration, but far from the only decision you’ll need to make.
In this session we will give an update on the most popular media servers to consider as well as go deeper into scalability with topics such as deployment using kubernetes/docker, persistence when using multiple SFU/MCU servers, and optimizations available with WebRTC for better performance.

MOdel-Driven Approach for design and execution of applications on multiple Cl...Marcos Almeida
Current Cloud’s offer is becoming day by day wider providing a vibrant technical environment, where SMEs can create innovative solutions and evolve their services. Clouds promise cheap and flexible services to end-users at a much larger scale than before.
The main goal of MODAClouds is to provide a decision support system along with design and runtime environments for early prototyping and automatic deployment of applications on multi-Clouds with guaranteed QoS. Model-driven development combined with novel model-driven risk analysis and quality of service prediction enable developers to specify Cloud-provider independent models enriched with quality parameters, implement these, perform quality prediction, monitor applications at run-time and optimize them based on the feedback, thus filling the gap between design and run-time. Additionally, MODAClouds provides techniques for data mapping and synchronization among multiple Clouds.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

# 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
