Join us as the Severalnines & Percona teams join forces for a different perspective on how to automate and manage your MongoDB or Percona Server for MongoDB databases. During this webinar, we’ll walk you through the key features of the Percona Server for MongoDB as compared to MongoDB itself as well as how to manage both “flavours” of MongoDB. There are many generic tools available, both commercial and open source, to aid with the automation of operational tasks. Some of these tools are even deployed in the database world. However, there are a small number of specialist domain-specific automation tools available, and we are going to compare the MongoDB-relevant functionality of two of these products: MongoDB’s Ops Manager, and ClusterControl from Severalnines. Attendees should take away a clear understanding of the differences between these tools, and how they help automate and manage MongoDB operations. AGENDA - Introduction to Percona Server for MongoDB - How to automate and manage MongoDB - Installation and maintenance - Complexity of architecture - Options for redundancy - Comparative functionality - Monitoring, Dashboard, Alerting - Backing up your deployments - Automated deployment of advanced configurations - Upgrading existing deployments SPEAKERS Ruairí Newman is passionate about all things cloud and automation and has worked for MongoDB, VMware and Amazon Web Services among others. He has a background in Operational Support Systems and Professional Services. Prior to joining Severalnines, Ruairí worked for Huawei Ireland as Senior Cloud Solutions Architect on their Web Services project, where he advised on commodity cloud architecture and Monitoring technologies, and deployed and administered a Research & Development Openstack lab. Prior to joining Percona as a Product Manager, Tyler Duzan spent almost 13 years as an operations and security engineer in a variety of different industries. Deciding to take his analytical mindset and strategic focus into new territory, Tyler is applying his knowledge to solving business problems for Percona customers with inventive solutions combining technology and services.

The Basics - Getting Started

Highly Available Ops Manager Architecture
In this scenario, a highly
available Ops Manager
requires 8 physical servers,
not including the HTTP load
balancer.
Apart from the HTTP
Services, the solution requires
3 MongoDB replica sets of 3
data nodes each;
One each for the Application
Database, and the Backup
Blockstore Databases #1 &
#2.

13. Copyright 2017 Severalnines ABCopyright 2017 Severalnines AB
ClusterControl uses a single MySQL /
MariaDB database server, to which
its core services connect to store and
retrieve data.
Redundancy can be achieved
through deploying a database
snapshot on a second node, and
installing the ClusterControl
applications.
With a HTTP proxy in front, requests
can be directed to the live node.
ClusterControl services such as
auto-recovery should be stopped on
the second node to avoid
complications.

Percona Server vs MongoDB Community Edition

23. Copyright 2017 Severalnines ABCopyright 2017 Severalnines AB
● Added to Percona Server for MongoDB in partnership with Facebook
● Based on the open-source RocksDB library derived from LevelDB
● Uses LSM-trees instead of B-trees for indexes, optimizes for write-heavy
workloads
● Has native support for Snappy, LZ4, and Zlib compression
● LSM-Trees are append-only, so are fast regardless of disk size or available
space.
● Writes go to Memtables first before being flushed to disk, reads are
serviced from memory if possible
● Compared to Wired Tiger, MongoRocks uses less disk space, maintains
higher insert rates, and has better response times.

● QAN for MongoDB was announced at Percona Live Europe in Dublin,
September 2017
● Query Profiling in the upstream implementation can incur significant
performance overhead
● Percona Server for MongoDB implements an optimized query profiler that
supports setting rate limits
● For example to profile all operations only for queries which are slower
than 200ms and every 100th fast query, you would do the following:
○ mongod --profile 2 --slowms 200 --rateLimit 100
● Integrates with Percona Toolkit using pt-mongodb-query-digest tool
