About Amazon s3

What is Amazon s3?

Amazon S3 (Simple Storage Service) is a cloud-based object storage service provided by Amazon Web Services (AWS). S3 provides a scalable and secure way to store and retrieve data from anywhere on the internet. It is designed to be highly available and durable, with an SLA that promises 99.999999999% (11 nines) of object durability.

S3 enables users to store and retrieve any amount of data, from anywhere in the world, through a simple web interface, APIs or AWS CLI. S3 stores data as objects, which are organized into buckets. A bucket is a container for objects, and you can think of it as a folder in a file system. Each object in S3 has a unique key, which identifies the object within the bucket.

S3 supports various features such as versioning, lifecycle policies, access control, security and compliance, and data transfer acceleration. S3 can also integrate with other AWS services such as Amazon Elastic Compute Cloud (EC2), AWS Lambda, AWS Glue, and more, to build powerful data processing and analysis pipelines.

S3 is widely used for a variety of use cases such as data backup and archive, big data analytics, media storage and distribution, and mobile and web application hosting, among others. S3 offers a pay-as-you-go pricing model, which makes it a cost-effective solution for businesses of all sizes.

Backup with Amazon S3?

There are several reasons why you should backup your MySQL database into Amazon S3:

  1. Durability and availability: Amazon S3 is designed to provide highly durable and available storage for your data. S3 stores data in multiple locations and automatically replicates data across different availability zones to ensure that your data is highly available and protected against data loss.
  2. Scalability: S3 provides unlimited storage capacity, which means that you can store as much data as you need. You can easily scale up or down your storage capacity based on your business needs, without having to worry about provisioning additional hardware or managing complex storage infrastructure.
  3. Cost-effectiveness: S3 offers a pay-as-you-go pricing model, which means that you only pay for the storage you use. This makes it a cost-effective solution for backing up your MySQL database, especially if you have large amounts of data to backup.
  4. Easy access and retrieval: S3 provides a simple web interface, APIs and AWS CLI to access and retrieve your data from anywhere in the world. This means that you can easily retrieve your data in case of a disaster or data loss event.
  5. Data processing and analysis: S3 can integrate with other AWS services such as AWS Glue, Amazon Athena, Amazon Redshift, and more, to build powerful data processing and analysis pipelines. This means that you can leverage the power of these services to process and analyze your data in the cloud, without having to manage your own data infrastructure.

Overall, backing up your MySQL database into Amazon S3 provides a reliable and scalable solution for protecting your critical data, while also enabling you to leverage the power of AWS services to process and analyze your data in the cloud.

Business scenario

  • Disaster Recovery: By backing up your MySQL database to Amazon S3, you can ensure that your data is protected in case of a disaster or data loss event. You can restore your data from S3 to a new database instance in case your original database becomes unavailable or corrupted.

  vanus-store-0                    1/1     Running   0          96s
  vanus-store-1                    1/1     Running   0          68s
  vanus-store-2                    1/1     Running   0          68s
  vanus-timer-5cd59c5bf-hmprp      1/1     Running   0          97s
  vanus-timer-5cd59c5bf-pqkd5      1/1     Running   0          97s
  vanus-trigger-7685d6cc69-8jgsl   1/1     Running   0          97s
  • Install vsctl (the command line tool).

    curl -O
    chmod ug+x vsctl
    mv vsctl /usr/local/bin
  • Set the endpoint for vsctl.

    export VANUS_GATEWAY=
  • Create an Eventbus to store your events.

    $ vsctl eventbus create --name mysql-s3-scenario
    |     RESULT     |       EVENTBUS      |
    | Create Success | mysql-email-scenario|

Step 2: Deploy the MySQL Source Connector

  • Enable binary logging if you have disabled it (MySQL default Enabled). Create a new USER and grant roles, choose a unique password for the user.
  CREATE USER 'vanus'@'%' IDENTIFIED WITH mysql_native_password BY 'PASSWORD';
  • Create the config file for MySQL in the Playground. Change MYSQL_HOST, MYSQL PORT, PASSWORD, DATABASE_NAME, and TABLE_NAME.
cat << EOF > config.yml
  target: # Vanus in Playground
  name: "quick_start"
  host: "MYSQL_HOST" # IP address of MySQL server
  port: MYSQL PORT # port address of MySQL server
  username: "vanus" # Username
  password: "PASSWORD" # Password previously set
  database_include: [ "<DATABASE_NAME>" ] # The name of your database

# format is vanus_test.tableName
table_include: [ "TABLE_NAME" ] # The name of your Table

type: FILE
pathname: "/vanus-connect/data/offset.dat"

db_history_file: "/vanus-connect/data/history.dat"
  • Run MySQL Source in the background
  docker run -it --rm --network=host \
  -v ${PWD}:/vanus-connect/config \
  -v ${PWD}:/vanus-connect/data \
  --name source-mysql &

Step 3: Deploy the S3 Sink Connector

  • To generate the YAML file for launching the S3 Sink connector in Kubernetes, execute the command provided bellow.
cat << EOF > s3-sink.yml
apiVersion: v1
kind: Service
 name: sink-aws-s3
 namespace: vanus
   app: sink-aws-s3
 type: ClusterIP
   - port: 8080
     name: sink-aws-s3
apiVersion: v1
kind: ConfigMap
 name: sink-aws-s3
 namespace: vanus
 config.yml: |-
   port: 8080
     access_key_id: AKIAIOSFODNN7EXAMPLE
     secret_access_Key: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
   region: "us-west-2"
   bucket: "mybucket"
   scheduled_interval: 10
apiVersion: apps/v1
kind: Deployment
 name: sink-aws-s3
 namespace: vanus
   app: sink-aws-s3
     app: sink-aws-s3
 replicas: 1
       app: sink-aws-s3
       - name: sink-aws-s3
         imagePullPolicy: Always
           - containerPort: 8080
               name: http
           - name: config
             mountPath: /vanus-connect/config
       - name: config
           name: sink-aws-s3

You can edit the configuration settings by opening the “s3-sink.yml” file in the vi text editor using the command “vi s3-sink.yml”. Once the file is opened in the editor, you can make any necessary modifications to the configuration parameters and save the changes before exiting the editor.

  • aws.access_key_id
  • aws.secret_access_key
  • region
  • bucket

vi s3-sink.yml

How to exit.

ESC Shift + : wq Enter

  • Run AWS S3 Sink in Kubernetes

kubectl apply -f s3-sink.yaml

Check out the results

Here is a short recap of the three steps involved in setting up a MySQL to S3 pipeline using Vanus:

Step 1: Deploy Vanus - Using the playground to install Vanus in Kubernetes.

Step 2: Start MySQL Connector - Configure and start the MySQL connector by providing the necessary database connection details, such as the hostname, port, username, and password, and configuring any necessary data filters.

Step 3: Start S3 Connector - Configure and start the S3 connector by providing the S3 bucket details, such as the bucket name and region, and configuring any necessary data transforms.

To connect the Vanus Eventbus to the S3 Sink, you will need to create a subscription that specifies the Eventbus and the target Sink. This can typically be done via the Vanus command line vsctl.

Here is the command to create a subscription:

vsctl subscription create \
--name quick-start \
--eventbus mysql-s3-scenario \
--sink 'http://sink-aws-s3:8080'
