Infrastructure choices - cloud vs colo vs bare metal
•
3 likes•1,058 views
This document discusses the differences between cloud, colocation, and bare metal infrastructure options. It covers key considerations for performance including CPU, memory, disk, and network latency and bandwidth. Colocation provides hardware at a specific location while maintaining internal skills, but has costs for total spend, hardware specifications, and power usage. Cloud infrastructure offers elastic workloads and support for demand spikes and unknown requirements, but bare metal is preferable for managed hardware replacement and networking needs. Overall, the best option depends on an organization's specific workload characteristics and skills.

Achieving the ultimate performance with KVM
This document summarizes an presentation about achieving ultimate performance with KVM. It discusses optimizing hardware, CPU, memory, networking, and storage for virtual machines. The goal is the lowest cost per delivered resource while meeting performance targets. Specific optimizations mentioned include CPU pinning, huge pages, SR-IOV networking, virtio drivers, and bypassing the host for storage. It cautions that many performance claims use unrealistic benchmarks and hardware configurations unlike real-world usage.
Is It Faster to Go with Redpanda Transactions than Without Them?!
P99 CONF
We all know that distributed transactions are expensive, have higher latency and lower throughput compared to a non-transactional workload. It's just common sense that when we ask a system to maintain transactional guarantees it should spend more time on coordination and thus have poorer performance, right?
Well, it's true that we can't get rid of this overhead. But at the same time each transaction defines a unit of work, so the system stops dealing with individual requests and becomes more aware about the whole workload. Basically it gets more information and may use it for new kinds of optimizations which compensate for the overhead.
In this talk I'll describe how Redpanda optimized the Kafka API and pushed throughput of distributed transactions up to eight times beyond an equivalent non-transactional workload while preserving sane latency.
Kinetic swift quick tour
This document discusses workload generation, tracing and analysis of disk performance on three sample drives with varying input-output operations per second and data throughput. It also contains graphs showing the distribution of sequential read operations and data transfer by size of sequential run for a Swift benchmark storing 20MiB objects. Later, the document discusses disaggregated storage and introduces Seagate's Kinetic Open Storage platform as a new open storage solution that separates hardware and software. It provides an overview of the Kinetic device model and functional API for distributed object storage.
Global deduplication for Ceph - Myoungwon Oh
Global deduplication for Ceph storage clusters can save up to 40% of total storage space by eliminating redundant data blocks. The document discusses two designs for implementing global deduplication in Ceph without adding a centralized metadata server: 1) using a double distribution hash to map data chunks to objects without redirection, and 2) storing deduplication metadata within self-contained objects to avoid complex linking between systems. It also describes the implementation of an extensible tier in Ceph for deduplication using object manifests and ongoing work to contribute these features to the upstream Ceph project. Remaining tasks are listed along with challenges around small chunk sizes and minimizing performance impacts.
Unikraft: Fast, Specialized Unikernels the Easy Way
P99 CONF
Unikernels are famous for providing excellent performance in terms of boot times, throughput and memory consumption, to name a few metrics. However, they are infamous for making it hard and extremely time consuming to extract such performance, and for needing significant engineering effort in order to port applications to them. We introduce Unikraft, a novel micro-library OS that (1) fully modularizes OS primitives so that it is easy to customize the unikernel and include only relevant components and (2) exposes a set of composable, performance-oriented APIs in order to make it easy for developers to obtain high performance.
Our evaluation using off-the-shelf applications such as nginx, SQLite, and Redis shows that running them on Unikraft results in a 1.7x-2.7x performance improvement compared to Linux guests. In addition, Unikraft images for these apps are around 1MB, require less than 10MB of RAM to run, and boot in around 1ms on top of the VMM time (total boot time 3ms-40ms). Unikraft is a Linux Foundation open source project and can be found at www.unikraft.org.

Storage based snapshots for KVM VMs in CloudStack
This document discusses storage-based snapshots for KVM VMs in CloudStack. It describes how CloudStack can leverage underlying storage providers' capabilities to take consistent snapshots of VMs and their disks while the VMs are running, regardless of disk format. This is done by freezing the VM, taking asynchronous snapshots of its disks, then unfreezing the VM. This provides faster, more space-efficient snapshots compared to CloudStack's default VM snapshot implementation for qcow disks. The technique works with various storage providers like NFS, Ceph, and StorPool.

Considering bare metal as a viable cloud option
Bare metal servers provide higher performance than virtual servers by avoiding hypervisor overhead and directly utilizing server hardware. This allows bare metal servers to achieve higher IOPS, throughput, network speeds, and CPU and disk performance. Bare metal servers also offer more consistent performance compared to nominal specifications for virtual servers.

Asynchronous design with Spring and RTI: 1M events per second
An application designer usually has to choose where to trade flexibility for specificity (and thus usually performance); knowing when and where to do so is an art and requires experience. This talk will share over a decades worth of experience making these decisions and the learnings from developing Pivotal's successful Real Time Intelligence (RTI) product using the latest versions of Spring projects: Integration, Data, Boot, MVC/REST and XD. A walk through the RTI architecture will provide the base for an explanation about how Spring performs at hundreds (and millions) of events/operations per second and the techniques that you can use right now in your own Spring applications to minimise resource utilisation and gain performance.
Memory, Big Data, NoSQL and Virtualization
In-memory processing has started to become the norm in large scale data handling. This is aclose to the metal analysis of highly important but often neglected aspects of memory accesstimes and how it impacts big data and NoSQL technologies.We cover aspects such as the TLB, the Transparent Huge Pages, the QPI Link, Hyperthreading and the impact of virtualization on high-memory footprint applications. We present benchmarks of various technologies ranging from Cloudera’s Impala to Couchbase and how they are impacted by the underlying hardware.The key takeaway is a better understanding of how to size a cluster, how to choose a cloud provider and an instance type for big data and NoSQL workloads and why not every core or GB of RAM is created equal.

Why puppet? Why now?
Why Puppet? Why now? Can you get by without using any config management? You probably think don't have time, or that your project is too small. What can using Puppet really add? How can you justify investing time up front? Maybe you can just do it later?
Getting started with config management can often seem like a big project, especially if you only manage a few systems or have a small team. This talk will examine why you should use Puppet from the beginning. It will examine what you can do with Puppet that couldn't do otherwise, how much time it will save and why it's especially important if you think your project has even the smallest chance of scaling in the future.
