VMworld 2014: Virtualize Active Directory, the Right Way!
Virtualizing Active Directory domain controllers can provide benefits like increased availability and scalability. However, there are some safety considerations to take into account, such as preventing "USN rollback" which occurs when a domain controller's state is reverted, like after restoring from a snapshot. New features in Windows Server 2012 and VMware vSphere help address this, such as the VM Generation ID which changes when the domain controller state is modified, triggering safety mechanisms to isolate changes. Proper configuration following best practices is important for successfully virtualizing Active Directory.

VM migration allows the transfer of virtual machines between physical servers while they are powered on (live migration) or powered off (cold migration). Live migration enables maintenance without disrupting service and helps balance server loads. It works by transferring a VM's memory, processor state, and devices from one host to another over the network in milliseconds without users noticing. Cold migration simply moves a powered-off VM's configuration files and disks to a new host. Both types simplify administration and improve hardware utilization.
12 best practices for virtualizing active directory DCs
The document outlines 12 best practices for virtualizing Active Directory domain controllers (AD DCs). It discusses why AD DCs are different from other workloads and should be virtualized carefully. The best practices include ensuring high availability of virtualized DCs, avoiding snapshots and clones of DCs, using backups that can restore objects and forests, preventing clock drift, and having anti-affinity rules and disaster recovery plans for DCs. Implementing these practices can make virtualizing DCs safer while gaining benefits of virtualization like high availability and migration capabilities.
Adding Value in the Cloud with Performance Test
This document discusses the importance of performance testing cloud applications and outlines best practices for defining performance requirements, testing methodology, and identifying issues. It provides examples of performance problems found in databases, applications, operating systems, and networks. The key goals of performance testing are to understand system behavior under load, find bottlenecks and hidden bugs, and verify that requirements are met.
LOAD BALANCING ALGORITHMS
This document discusses client-side load balancing in a cloud computing environment. It describes how a client-side load balancer can distribute requests across backend web servers in a scalable way without requiring control of the infrastructure. The proposed architecture uses static anchor pages hosted on Amazon S3 that contain JavaScript code to select a web server based on its reported load. The JavaScript then proxies the request to that server and updates the page content. This approach achieves high scalability and adaptiveness without hardware load balancers or layer 2 optimizations.
XenApp Load Balancing
The document discusses load balancing and intelligent load balancing. It covers load balancing architecture, how the data collector and dynamic store work, and how performance counters are used. Intelligent load balancing techniques like load throttling are explained. Potential issues that could cause load imbalances like the "black hole effect" or failing to read performance counters are also reviewed. Troubleshooting techniques for resolving common problems are provided.

This document discusses high availability strategies for MariaDB databases. It defines high availability as a system that is continuously operational for a desirably long period of time. It then examines different levels of availability based on uptime percentages and corresponding downtime. Various high availability components are described, including data redundancy, failover/switchover solutions, and monitoring. Asynchronous and synchronous replication techniques are summarized, along with how MaxScale can implement read/write splitting and failover automation. The benefits and limitations of Galera cluster synchronous replication are also provided.
Architecting for the cloud elasticity security
Concurrency and state management are important considerations for achieving elasticity in cloud systems. There are three types of state: session state kept by clients, server-side state kept in processes, and persistent state stored externally. Server-side state makes scaling difficult, while stateless servers allow elasticity. Memcached provides a way to synchronize small amounts of in-memory state across servers to support stateless services running elastically in the cloud.
Nagios Conference 2012 - Jason Cook - Nagios and Mod-Gearman
Verisign moved from a passive Nagios monitoring setup using NSCA to an active setup using Nagios, Gearman, and other tools to address challenges with scaling, freshness checking, and lack of centralized scheduling. The new active setup using virtual machines with Nagios, Gearman, Mod-Gearman, and other components provided better performance, handling over 20,000 checks per minute using only 6 VMs, and offered more flexibility and control over monitoring.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
