Straight-through cables connect pins on one end of the cable to the same pins on the other end, allowing connection between a computer and a switch, hub, or another computer. Crossover cables have crossed wire pairs and are used to connect like devices such as two computers or two routers. Rollover cables have opposite wiring on each end and connect a device to a router or switch's console port for programming. The document also discusses IP addressing and subnetting concepts.
(ARC204) Architecting Microsoft Workloads on AWS | AWS re:Invent 2014Amazon Web Services
Are you interested in implementing key Microsoft workloads such as Windows Server, Active Directory, SQL Server, or SharePoint Server on AWS? Have you wondered how to securely manage your Microsoft-based workloads on AWS? In this session, we step you through the architectural considerations, implementation steps, and best practices for deploying and administering these key Microsoft workloads on the AWS cloud. Find out how to deploy these workloads on your own, or by using automated solutions such as AWS Quick Start. Hear how existing AWS customers have successfully implemented Microsoft workloads on AWS and walk away with a better idea of how to implement or migrate your Microsoft-based workloads to AWS.
In this session, we will walk through the fundamentals of Amazon Virtual Private Cloud (VPC). First, we will cover build-out and design fundamentals for VPC, including picking your IP space, subnetting, routing, security, NAT, and much more. We will then transition into different approaches and use cases for optionally connecting your VPC to your physical data center with VPN or AWS Direct Connect. This mid-level architecture discussion is aimed at architects, network administrators, and technology decision-makers interested in understanding the building blocks AWS makes available with VPC and how you can connect this with your offices and current data center footprint.
High-availability web server clusters use redundancy to ensure continuous service if any single component fails. They distribute workload across multiple servers for improved efficiency and scalability. The document proposes using Linux Virtual Server to implement such a cluster, with virtual servers distributing requests to real servers via network address translation, direct routing, or IP tunneling. Hardware requirements include servers, switches, and cabling to physically set up the redundant infrastructure.

Midokura OpenStack Day Korea Talk: MidoNet Open Source Network Virtualization...Dan Mihai Dumitriu
OpenStack deployments for public or private clouds require overlay networking. Due to the scale and rate of change of virtual resources, it isn't practical to rely on traditional network constructs and isolation mechanims. Today's deployments require performance, resilience, and high availability to be considered truly production-ready. In this session, we deep dive into the MidoNet architecture, and process of sending a data packet across an OpenStack environment through a network overlay. A distributed architecture implements logical constructs that are used to build networks without a single point of failure, all while adding network functionality in a highly-scalable manner. Network functions are applied in a single virtual hop. By applying network services right at the ingress host, the network is free from unnecessary clogging and bottlenecks by avoiding additional hops. Packets reach their destination more efficiently with the single virtual hop. After this session, the audience will understand how distributed architectures allow efficient networking with routing decisions and network services applied at the edge. Also, the audience will understand how it is easier to scale clouds when the network intelligence is distributed.

On the other hand, cloud API costs related to GET/LIST operations and cross-region data transfer add up quickly.
The newly introduced Trino file system cache by Alluxio aims to overcome the above challenges. In this session, Jianjian will dive into Trino data caching strategies, the latest test results, and discuss the multi-level caching architecture. This architecture makes Trino 10x faster for data lakes of any scale, from GB to EB.
What you will learn:
- Challenges relating to the speed and costs of running Trino in the cloud
- The new Trino file system cache feature overview, including the latest development status and test results
- A multi-level cache framework for maximized speed, including Trino file system cache and Alluxio distributed cache

- The future roadmap of Trino file system cache and Trino-Alluxio integration
Why Apache Kafka Clusters Are Like Galaxies (And Other Cosmic Kafka Quandarie...Paul Brebner
Closing talk for the Performance Engineering track at Community Over Code EU (Bratislava, Slovakia, June 5 2024) https://eu.communityovercode.org/sessions/2024/why-apache-kafka-clusters-are-like-galaxies-and-other-cosmic-kafka-quandaries-explored/ Instaclustr (now part of NetApp) manages 100s of Apache Kafka clusters of many different sizes, for a variety of use cases and customers. For the last 7 years I’ve been focused outwardly on exploring Kafka application development challenges, but recently I decided to look inward and see what I could discover about the performance, scalability and resource characteristics of the Kafka clusters themselves. Using a suite of Performance Engineering techniques, I will reveal some surprising discoveries about cosmic Kafka mysteries in our data centres, related to: cluster sizes and distribution (using Zipf’s Law), horizontal vs. vertical scalability, and predicting Kafka performance using metrics, modelling and regression techniques. These insights are relevant to Kafka developers and operators.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.
