Webinar October 4, 2017: Databases in the Hosted Cloud

Databases in the Hosted Cloud 1

Join Percona’s Chief Evangelist, Colin Charles as he presents Databases in the Hosted Cloud on Wednesday, October 4, 2017, at 7:00 am PDT / 10:00 am EDT (UTC-7).Databases in the Hosted Cloud 1


Today you can use hosted MySQL/MariaDB/Percona Server for MySQL/PostgreSQL in several “cloud providers” as a database as a service (DBaaS). Learn the differences, the access methods and the level of control you have for the various public databases in the hosted cloud offerings:

  • Amazon RDS including Aurora
  • Google Cloud SQL
  • Rackspace OpenStack DBaaS
  • Oracle Cloud’s MySQL Service

The administration tools and ideologies behind each are completely different, and you are in a “locked-down” environment. Some considerations include:

  • Different backup strategies
  • Planning for multiple data centers for availability
  • Where do you host your application?
  • How do you get the most performance out of the solution?
  • What does this all cost?
  • Monitoring

Growth topics include:

  • How do you move from one DBaaS to another?
  • How do you move from a DBaaS to your own hosted platform?

Register for the webinar here.

Percona Live Europe Featured Talks: Monitoring Open Source Databases with Icinga with Bernd Erk

Percona Live Europe 2017

Percona Live EuropeWelcome to another post in our series of interview blogs for the upcoming Percona Live Europe 2017 in Dublin. This series highlights a number of talks that will be at the conference and gives a short preview of what attendees can expect to learn from the presenter.

This blog post is with Bernd Erk, CEO of Icinga. His talk is titled Monitoring Open Source Databases with Icinga. Icinga is a popular open source successor of Nagios that checks hosts and services, and notifies you of their statuses. But you also need metrics for performance and growth to deal with your scaling needs. Adding conditional behaviors and configuration in Icinga is not just intuitive, but also intelligently adaptive at runtime. In our conversation, we how to intelligently monitor open source databases:

Percona: How did you get into database technology? What do you love about it?

Bernd: I started a position as a junior systems engineer in a large German mail order company. They were totally committed to Oracle databases and the tool stack around it. As Linux gained more and more attention, we became aware of MySQL very early and were fascinated by the simplicity of installation and administration. There were of course so many things Oracle had in those days that MySQL didn’t have, but most of our uses also didn’t require those extra (and of course expensive) features.

Percona: You’re presenting a session called “Monitoring Open Source Databases with Icinga”. Why is monitoring databases important, and what sort of things need to be monitored?

Bernd: Usually databases are a very important part of an IT infrastructure, and need to be online 24/7. I also had the personal experience of database downtime putting a lot of pressure on both the organization in general and the team in charge. Since most open source databases provide very good interfaces, it is not so hard to figure out if they are up and running. Like in many monitoring arenas, knowing what to monitor is the important information.

In addition to the basic local and remote availability checks, monitoring database replication is very important. We often see environments where the standby slave is outdated by, years or not able to keep up with the incoming load. From there you can go into databases and application metrics to learn more about performance and IO behavior.

Percona: Why are you using Icinga specifically? What value does it provide above other monitoring solutions?

Bernd: I’ve been involved with Icinga from the beginning, so it is my number one choice in open source monitoring. In my opinion, the great advance of Icinga 2 is the simplicity of legacy systems like Nagios (or Icinga 1), but also its support for complex environments (such as application-based clustering). There is also the live configuration of the Icinga 2 monitoring core through our REST API. With all the supported tools for metrics, logs and management around it, for me Icinga 2 is the best match for open source monitoring.

Percona: What do you want attendees to take away from your session? Why should they attend?

Bernd: Attendees will get a short overview on Icinga 2, and why it is different to Nagios (Icinga 1). I will also guide them through practical monitoring examples and show implemented checks in a live demo. After my talk, they should be able to adapt and extend on-premise or cloud monitoring with Icinga 2 using the default open source plugins.

Percona: What are you most looking forward to at Percona Live Europe 2017?

Bernd: Getting together with the great database community in all aspects, and going to Dublin (to be honest). I have never been there, and so it is my first time.

Percona Live Featured Session with Casper Kejlberg-Rasmussen: Placing Databases @ Uber

Percona Live Featured Session

Percona Live Featured SessionWelcome to another post in the series of Percona Live featured session blogs! In these blogs, we’ll highlight some of the session speakers that will be at this year’s Percona Live conference. We’ll also discuss how these sessions can help you improve your database environment. Make sure to read to the end to get a special Percona Live 2017 registration bonus!

In this Percona Live featured session, we’ll meet Casper Kejlberg-Rasmussen, Software Developer at Uber. His session is Placing Databases @ Uber. Uber has many thousands of MySQL databases running inside of Docker containers on thousands of hosts. When deciding exactly which host a database should run on, it is important that you avoid hosts running databases of the same cluster as the one you are placing, and that you avoid placing all databases of a cluster on the same rack or in the same data center.

I had a chance to talk to Casper about Uber and database placement:

CasperPercona: How did you get into database technology? What do you love about it?

Casper: When I took my Ph.D., my thesis area was about dynamic data structures. During my bachelor, master and Ph.D., I took all the algorithms and data structure classes I could. So it was natural for me to also work with databases in my professional career. Databases are a prime example of a very useful dynamic data structure.

Percona: Your talk is called Placing Database @ Uber. What do you mean by placing databases, and why is it important?

Casper: At Uber, the storage team manages all of Uber’s storage offerings. Our main database technology is an in-house NoSQL database called Schemaless. Schemaless builds on top of MySQL (and we specifically use our own fork of Percona’s MySQL variant, found here in GitHub). We have many thousands of databases that run inside of Docker containers. Whenever we need to create a new Schemaless instance for our internal customers, or we need to add capacity to an existing Schemaless instance, we need to place new Docker containers with Percona Server for MySQL running inside. For our Schemaless instances to be reliable, durable and highly available, we need to place databases in at least two different data centers. We want to avoid placing two databases of the same instance on the same rack or the same host. So consideration needs to be taken when deciding where to place the databases.

Percona: What are some of the conditions that affect where you place databases?

Casper: When we place a database we have to take into account the labels on the hosts we consider. These labels can be which data center or rack the host is part of, or what Clusto (Clusto is an internal hardware management tool we have) pools a host belongs to. This can be a testing, staging or production host, etc. A host also has “relations.” A relation is also a label, but instead of stating facts about the host, a relation states what other databases are running on the host. An example of a relation label is schemaless.instance.mezzanine, which indicates that the host is running a Schemaless database from the Mezzanine instance. Another example is schemaless.cluster.percona-cluster-mezzanine-us1-db01, which indicates that the database is a Schemaless database belonging to the cluster percona-cluster-mezzanine-us1-db01.

Percona: What do you want attendees to take away from your session? Why should they attend?

Casper: I want the attendees to remember that there are three steps when placing a database or any container:

  1. Filter out any host that fails the hard requirements (like not having enough resources) or fails the label or relation requirements (like having databases of the same instance as the one we want to place)
  2. Rank the hosts to select the best one, which can be having a host with the most free space left or having a low number of other databases on it
  3. As time passes and databases consume more resources, we want to relocate databases to other hosts at which it makes more sense to place them.

People should attend my session to see how to get good database placements in a simple way.

Percona: What are you most looking forward to at Percona Live 2017?

Casper: I look forward to hearing about other NoSQL solutions, and hearing about different storage engines for MySQL systems. And of course meeting other exciting people from the database community! ?

Open Source Databases at Percona Live Europe, Amsterdam

Percona Live Europe

Percona Live EuropeIn this blog post, I’ll review some of the open source database technologies discussions at Percona Live Europe.

I’ve already written about the exciting PostgreSQL and MongoDB content at Percona Live Europe in Amsterdam, and now I’m going to highlight some of our open source database content.  

In the last five years, the open source database community has been flourishing. There has been an explosion of creativity and innovation. The community has created many niche (and not so niche) solutions for various problems.

As a software engineer or architect, the number of available database options might excite you. You might also be intimidated about how to make the right technology choice. At Percona Live Europe, we have introductory talks for the relevant technologies that we find particularly interesting. These talks will help expand your knowledge about the available solutions and lessen intimidation at the same time.

I’m looking forward to the exciting technologies and talks that we’ll cover this year, such as:

For talks and tutorials on specific uses cases, check out the following sessions:

  • RocksDB is a very cool write optimized (LSM) storage engine, one of the few that has been in more than one database. In addition to the RocksDB-based systems inside Facebook, it can be used with MongoDB as MongoRocks and MySQL as MyRocks. It is also used inside next-generation database systems such as CockroachDB and TiDB. We have a lot of talks about RocksDB and related integrations, ranging from a MyRocks Tutorial by Yoshinori Matsunobu, to talk about MongoRocks by Igor Canadi, and a performance-focused talk by Mark Callaghan.
  • Elastic is the leading technology for open source full-text search implementations (hence previous name ElasticSearch) — but it is much more than that. ElasticSearch, Kibana, Logstash and Beats allow you to get data from a variety of data searches and analyze and visualize it. Philip Krenn will talk about full-text search in general in his Full-Text Search Explained talk, as well as talk in more details about ElasticSearch in ElasticSearch for SQL Users.
  • I am sure you’ve heard about Redis, the Swiss army knife of different data structures and operations. Redis covers many typical data tasks, from caching to maintaining counters and queues. Justin Starry will talk about Redis at Scale in Powering Million of live streams at Periscope, and Itamar Haber will talk about Extending Redis with Modules to make Redis an even more powerful data store.
  • Apache Spark is another technology you’ve surely heard about. Apache Spark adoption has skyrocketed in recent years due to its high-performance in-memory data analyses, replacing or supplementing Hadoop installations. We will hear about Badoo’s experience processing 11 billion events a day with Spark with Alexander Krasheninnikov, and also learn how to use Spark with MongoDB, MySQL and Redis with Tim Vaillancourt.
  • Apache Cassandra is a database focused on high availability and high performance, even when replicating among several data centers. When you think “eventual consistency,” perhaps Cassandra is the first technology that comes to mind. Cassandra allows you to do some impressive things, and Duy Hai Doan will show us some of them in his talk 7 things in Cassandra that you cannot find in RDBMS.
  • ClickHouse is a new guy on the block, but I’m very excited about this distributed column store system for high-performance analytics. Built by the Yandex team to power real-time analytics on the scale of trillions of database records, ClickHouse went open source earlier this year. Victor Tarnavsky will share more details in his talk.
  • Apache Ignite is another new but very exciting technology. Described as in-memory data fabric, it can be used for a variety of applications to supplement or replace relational databases — ranging from advanced data caching strategies to parallel in-memory processing of large quantities of data. Christos Erotocritou will talk about some of these use cases in his talk Turbocharge Your SQL Queries In-Memory with Apache Ignite.
  • RethinkDB is an interesting OpenSource NoSQL database built from the ground up for scalable real-time applications. The end-to-end real-time data streaming feature is really cool, and allows you build interactive real-time applications much easier. Ilya Verbitskiy will talk about RethinkDB in his Agile web-development with RethinkDB talk.
  • CockroachDB is a distributed database focused on survivability and high performance (borrowing some ideas from Google’s innovative Spanner database). Marc Berhault will talk database rocket science in his Inside CockroachDB’s Survivability Model.
  • TiDB is another open source NewSQL database, inspired by Google Spanner and F1. It can use a variety of storage engines for data store, and it supports MySQL wire protocol to ease application migration. Max Liu explains How TiDB was built in his talk.
  • ToroDB is a very interesting piece of technology. It is protocol-compatible with MongoDB, but stores data through a relational format in PostgreSQL. This can offer substantial space reduction and performance improvements for some workloads. Álvaro Hernández from 8Kdata will discuss this technology in his ToroDB: All your MongoDB data are belong to SQL talk.

As you can see we cover a wealth of exciting open source database technologies at Percona Live Europe. Do not miss a chance to expand your database horizons and learn about new developments in the industry. There is still time to register!
