Using AWS EC2 instance store vs EBS for MySQL: how to increase performance and decrease cost

If you are using large EBS GP2 volumes for MySQL (i.e. 10TB+) on AWS EC2, you can increase performance and save a significant amount of money by moving to local SSD (NVMe) instance storage. Interested? Then read on for a more detailed examination of how to achieve cost-benefits and increase performance from this implementation.

EBS vs Local instance store

We have heard from customers that large EBS GP2 volumes can be affected by short term outages—IO “stalls” where no IO is going in or out for a couple of minutes. Statistically, with so many disks in disk arrays (which back EBS volumes) we can expect frequent disk failures. If we allocate a very large EBS GP2 volume, i.e. 10Tb+, hitting such failure events can be common.

In the case of MySQL/InnoDB, such an IO “stall” will be obvious, particularly with the highly loaded system where MySQL needs to do physical IO. During the stall, you will see all write queries …

Amazon Aurora Serverless - Features, Limitations, Glitches

Amazon Aurora Serverless — Features, Limitations, Glitches

Finally after an year AWS announced the AWS Aurora Serverless MySQL compatibility. I was expecting that they will release this in the reInvent 2018, but it live now. So now I’m expecting more new features for Aurora servers in the reInvent 2018. I have played with this baby and understood whats is doing and what we can do with that.

Here is the blog from AWS about Aurora Serverless

Aurora Serverless MySQL Generally Available | Amazon Web Services

What is Aurora Serverless?

Aurora serverless provides seamlessly scale up and down its compute and memory. You can pay for how much resources that you have been used. No needs of creating and managing the Read Replica and HA(Multi-AZ).

Amazon Web Services (AWS) Aurora is one of the most popular cloud-based RDBMS solutions. The main reason for Aurora’s success is because it’s based on InnoDB storage engine.

In this session, we will talk about how you can efficiently plan for migration to Aurora using Terraform and Percona products and solutions. We will share our Terraform code for launching AWS Aurora clusters, look at tricks for checking data consistency, verify migration paths and effectively monitor the environment using PMM.

Database Objects migration to RDS/ Aurora (AWS)

The world of application and its related services are migrating more towards cloud, because of availability, Elasticity, Manageability etc. While moving the entire stack we need to be very cautious while migrating the database part.

Migration of DB servers is not a simple lift and shift operation, Rather it would require a proper planning and more cautious in maintaining data consistency with existing DB server and cloud server by means of native replication or by using any third party tools.

The best way to migrate the existing MySQL database to RDS, in my opinion, is by using “logical backup“. Some of the logical backup tools as below,

Mysqldump — single threaded (widely used)

Amazon RDS Multi-AZ Deployments and Read Replicas

Amazon RDS is a managed relational database service that makes it easier to set up, operate, and scale a relational database in the cloud. One of the common questions that we get is “What is Multi-AZ and how it’s different from Read Replica, do I need both?”.  I have tried to answer this question in this blog post and it depends on your application needs. Are you looking for High Availability (HA), read scalability … or both?

Before we go to into detail, let me explain two common terms used with Amazon AWS.

Region – an AWS region is a separate geographical area like US East (N. Virginia), Asia Pacific (Mumbai), EU (London) etc. Each AWS Region has multiple, isolated locations known as Availability Zones.

Availability Zone (AZ) – AZ is simply one or more data …

MySQL to Amazon Redshift Replication.

In our work, We used to get a lot of requirements for replicating data from one data source to another. Our team provided solutions to replicate data from MySQL to Vertica, Amazon Redshift, Hadoop. Out of which Amazon Redshift replication is a bit complicated as Amazon Redshift is a Database as a service (DBaaS) and the process is not straightforward.

So, I take this opportunity to guide on how to replicate the specific set of tables from MySQL to AWS Redshift using Tungsten replicator.

1.0. Tungsten Replicator:

Tungsten Replicator is an open source replication engine supports data extract from MySQL, MySQL Variants such as RDS, Percona Server, MariaDB and Oracle and allows the data extracted to be applied on other data sources such as Vertica, Cassandra, …

How to Automate Minor Version Upgrades for MySQL on RDS

Amazon RDS for MySQL offers the option to automate minor version upgrades using the minor version upgrade policy, a property that lets you decide if Amazon is allowed to perform the upgrades on your behalf. Usually the goal is not to upgrade automatically every RDS instance but to keep up to date automatically non-production deployments. This helps you address engine issues as soon as possible and improve the automation of the deployment process.

If your are using the AWS Command Line Interface (CLI) and you have an instance called test-rds01 it is as simple as changing

[--auto-minor-version-upgrade | --no-auto-minor-version-upgrade]

For example:

aws rds modify-db-instance --db-instance-identifier test-rds01 --apply-immediately …
