What is AWS RDS MariaDB?

– AWS RDS MariaDB is one of the most well-known open source relational databases

-AWS RDS MariaDB was created by MySQL developers.

– AWS RDS simplifies the process of setting up, operating, and scaling MariaDB server deployments that are made in the cloud.

– AWS RDS, allows you to start deploying scalable MariaDB cloud databases in just a couple of minutes while guarantying cost-efficiency and hardware capacity of re-sizable nature.

– AWS RDS gives you the possibility to start focusing on your application since it has the ability to manage your time-consuming database administration tasks. (Replication, software patching, backup, scaling and monitoring)

– AWS RDS supports the following MariaDB Server versions:

MariaDB Server Version 10.0

MariaDB Server Version 10.1

MariaDB Server version 10.2

MariaDB Server version 10.3

This implies that the coding, tools and apps which you are currently using are capable of being utilized with AWS RDS.

Advantages of Using AWS RDS MariaDB:

AWS RDS MariaDB – Using AWS RDS MariaDB

– Highly available

AWS RDS for MariaDB will simplify the use of replication for improving reliability and availability for your production workloads. Through Multi-Availability Zone option for deployment, you will be able to begin running mission critical workloads having the characteristics of being highly available with a built-in fail-over that works automatically.

– Acceptable prices

AWS RDS for MariaDB allows you to pay for just the resources which you choose to provision. You shall not encounter any upfront investments in selected hardware or high-costing technical resources. The availability of On-Demand pricing allows you to avoid any long term commitments and up-front costs of any kind, and you can even receive very great discounted rates through using Reserved Instance pricing.

– Easily scalable

Scaling an RDS for MariaDB instance can be made for 32 vCPUs with 244 GiB of Memory. Additionally, you will be capable of adding 6 read replicas for even more scaling read capacity. Scaling up the database storage can be done with 0 downtime along with scaling up throughput I case of utilizing RDS provisioned IOPS.

– Easy to apply security

AWS RDS simplifies the implementation of database security for your MariaDB database, by the isolation of data within a VPC and is capable encrypt data in-transit automatically. Data at rest is capable of being encrypted through the use of user managed encryption keys. Encrypting and decrypting processes will be taken care of transparently for not asking you to be the one responsible of modifying your app to be able to access data.

– RDS DB Instances that are outside of the VPC:

For data transferred between an EC2 instance and RDS DB Instance in differing AZs of the exact Region= No Data Transfer cost for the traffic coming in or going out of an RDS DB Instance.

You will merely have to pay for Data Transferred inside or outside of an EC2 instance, as well as standard EC2 Regional Data Transfer billing are going to be applied at the rate of $.01 for every GB in or out.

– RDS DB Instances that are inside the VPC:

Data which gets transferred between an EC2 instance and an RDS DB Instance located in differing AZs at a same AWS Region, will get billed for EC2 Regional Data Transfer costs on both ends of this transfer.

– DB Snapshot Copy will bill you for data transferred for the sake of copying snapshot’s data across AWS Regions. Upon copying the snapshot, there will be costs of standard database snapshot charges for storing this snapshot in a destination region.

Terraform AWS RDS

What is Terraform AWS RDS?

Terraform AWS RDS – Terraform AWS RDS Process

Terraform is a tool utilized for the following purposes:

– Building infrastructure

– Versioning infrastructure

– Changing infrastructure

– Treating infrastructure as if it were code

– Defining infrastructure through HashiCorp’s HCL language

– Checking configurations into source control

– Updating resources through Terraform for planning and applying changes

– Acting as an abstraction layer of infrastructure

Terraform AWS RDS – Terraform AWS RDS Infrastructure Layer

Terraform AWS RDS Characteristics:

– Terraform is Not a strong abstraction

– Terraform makes use of various providers for differing services.

– Terraform isn’t agnostic

– Gives the ability to easily alter your provider to be Google Cloud then to apply the exactly similar Terraform

– Gives you an organized description of infrastructure

– Gives you the ability to port infrastructure code to another provider exactly like porting your software to another language

What are Terraform AWS RDS modules?

Terraform AWS RDS – Terraform AWS RDS Module

A lot of instances are going to get configured for every single type of resource which means it’s certain that there will be a lot of copies of your code.

Further, you may want to create Specific resources together like parameter groups, database instances or PGBouncer services.

For the sake of supporting such types of reuse, Terraform gives you the ability to start creating something called “modules”.

Terraform modules are reusable blocks of Terraform code having both inputs and outputs (similar to a function in software).

Terraform modules add an even additional layer of abstraction between you and resources. Which means that the layer is capable of getting as deep as required because modules may reference different modules.

How to use Terraform and RDS defaults?

Is a truly simple process when creating an RDS instance by placing the below in an HCL file (like rds.tf):

resource “aws_db_instance” “muffy-test” {
allocated_storage    = 100
db_subnet_group_name = “db-subnetgrp”
engine               = “postgres”
engine_version       = “11.5”
identifier           = “muffy-test”
instance_class       = “db.m5.large”
password             = “password”
skip_final_snapshot = true
storage_encrypted    = true
username             = “postgres”
}

A lot of additional attributes may be specified, but the ones stated above are good enough to begin with.

What is Terraform AWS RDS plan?

Terraform AWS RDS – Terraform AWS RDS Plan

Right now, it’s time to start running the terraform plan. The plan displays the Terraform to be created in AWS. Acknowledge the values which did not get set in rds.tf which are going to be set or going to be “known after apply”. Those will be supplied using Terraform provider in italics or the RDS in simple plain text. Values which are set in HCL will turn bold.

Below you can find a generated execution plan.
The following symbols show resource actions:

+ create# aws_db_instance.muffy-test will be created

+ vpc_security_group_ids                = (known after apply)
}Plan: 1 to add, 0 to change, 0 to destroy.

What is Terraform AWS RDS apply?

After everything, you must go and apply the plan through using terraform apply.

% terraform apply .terraform.output
Time to acquire the state lock. This could require a couple of moments waiting…
aws_db_instance.muffy-test: Creating…
aws_db_instance.muffy-test: Still creating… [10s elapsed]

aws_db_instance.muffy-test: Creation complete after 2m39s [id=muffy-test]Apply complete! Resources: 1 added, 0 changed, 0 destroyed.
time to release the state lock. This could require a couple of moments waiting…

The creation of the above instance merely needed a couple of minutes to finish, but a lot of the instances created will take up to thirty to forty minutes. To view how the creation takes place using your command line will be a lot simpler than constantly refreshing the console in browser.

What is Terraform AWS RDS state?

Terraform AWS RDS – Terraform Logo

Upon the results of the apply finally appearing, you will notice that Terraform will not let you check all the values set on the instance. This means that you would have to view the created values using the console or through the use of terraform state show.

Check out the output of show down below and look at the number of values which had been set for you through either Terraform provider in italic or using the RDS itself in plain text. Merely values written in bold had been clearly set in the following rds.tf file:

AWS Lambda RDS

AWS Lambda RDS – AWS Lambda Function Access to RDS MySQL Instance

Here are the steps for giving your Lambda function the ability to access an RDS MySQL instance in the VPC.

Step One: Creating Execution Role

AWS Lambda RDS – AWS Lambda Function Execution Role

To create the execution role which grants your function permission for accessing AWS resources, follow the steps below.

For creating an execution role

Head straight to the roles page which is in the IAM console.
Click on Create role.
Go ahead and start creating a role having the below states properties.
- Role name: lambda-vpc-role.
- Trusted entity: Lambda.
- Permissions: AWSLambdaVPCAccessExecutionRole.

AWSLambdaVPCAccessExecutionRole – includes permissions for the function to start managing network connections to a VPC.

Step Two: Creating an AWS RDS database instance

In the following steps, we will be creating with the example Lambda function a table named Employee, enter a couple of records, then retrieve those records.

The table which will be created by the Lambda function includes the below schema:

Employee(EmpID, Name)

EmpID refers to the primary key. Currently, you must add a couple of new records to the table.

Firstly, an RDS MySQL instance needs to be launched in the default VPC with ExampleDB database. In case you possess an RDS MySQL instance which runs in your default VPC, you should ignore this step.

An RDS MySQL instance may be launched through 1 of the below methods:

Go over the steps for creating a MySQL DB instance then going ahead with connecting it to a database on a MySQL DB instance.
Utilize the below mentioned CLI command:

$ aws rds create-db-instance –db-name ExampleDB –engine MySQL \

–db-instance-identifier MySQLForLambdaTest –backup-retention-period 3 \

–db-instance-class db.t2.micro –allocated-storage 5 –no-publicly-accessible \

–master-username username –master-user-password password

Type in the name of the database, the name of the user name, and its password. A host address of the DB instance is required, and it’s given to you through the RDS console. You may possibly require to keep waiting for the instance status to become available as well as for the Endpoint value to show up in the console.

Step Three: Creating deployment package

AWS Lambda RDS – AWS Lambda Function Creating Deployment Package

In the below example Python code you can run a SELECT query over the table of Employee in the MySQL RDS instance which you had created in the VPC. A table will be created using the code in the ExampleDB database, sample records will be added and retrieved.

Example app.py

import sys

import logging

import rds_config

import pymysql

#rds settings

rds_host = “rds-instance-endpoint”

name = rds_config.db_username

password = rds_config.db_password

db_name = rds_config.db_name

logger = logging.getLogger()

logger.setLevel(logging.INFO)

try:

conn = pymysql.connect(rds_host, user=name, passwd=password, db=db_name, connect_timeout=5)

except pymysql.MySQLError as e:

logger.error(“ERROR: Unexpected error: Could not connect to MySQL instance.”)

logger.error(e)

sys.exit()

logger.info(“SUCCESS: Connection to RDS MySQL instance succeeded”)

def handler(event, context):

“””

This function gets you specific content from MySQL RDS instance

“””

item_count = 0

with conn.cursor() as cur:

cur.execute(“create table Employee ( EmpID int NOT NULL, Name varchar(255) NOT NULL, PRIMARY KEY (EmpID))”)

cur.execute(‘insert into Employee (EmpID, Name) values(1, “Joe”)’)

cur.execute(‘insert into Employee (EmpID, Name) values(2, “Bob”)’)

cur.execute(‘insert into Employee (EmpID, Name) values(3, “Mary”)’)

conn.commit()

cur.execute(“select * from Employee”)

for row in cur:

item_count += 1

logger.info(row)

#print(row)

conn.commit()

return “Added %d items from RDS MySQL table” %(item_count)

When you execute pymysql.connect() outside of the handler your function will be able to use the database connection once again for a more enhanced performance.

Another file will include connection data regarding the function.

Example rds_config.py

#config file containing credentials for RDS MySQL instance

db_username = “username”

db_password = “password”

db_name = “ExampleDB”

Dependencies

pymysql –This library is utilized by the lambda function for accessing the MySQL instance.

Start installing dependencies using Pip then creating a deployment package.

Step Four: Creating Lambda function

AWS Lambda RDS – Creating an AWS Lambda Function

Go ahead with creating your Lambda function using the create-function command.

$ aws lambda create-function –function-name CreateTableAddRecordsAndRead –runtime python3.8 \

–zip-file fileb://app.zip –handler app.handler \

–role arn:aws:iam::123456789012:role/lambda-vpc-role \

–vpc-config SubnetIds=subnet-0532bb6758ce7c71f,subnet-d6b7fda068036e11f,SecurityGroupIds=sg-0897d5f549934c2fb

Step Five: Testing Lambda function

AWS Lambda RDS – AWS Lambda Function Testing

Now, you need to start invoking the Lambda function manually through the invoke command. Upon executing the Lambda function, it is going to run the SELECT query over the Employee table in the RDS MySQL instance then print the results that will be sent to CloudWatch Logs.

Start by invoking the Lambda function using the invoke command.

$ aws lambda invoke –function-name CreateTableAddRecordsAndRead output.txt

Make sure that the Lambda function had been executed in a successful way through doing the following:
- Check the output.txt file.
- Go over the results found in the Lambda console.
- Make sure of the results in CloudWatch Logs.

After finally creating a Lambda function which is capable of accessing a database found in your VPC, you will be able to invoke this function invoked in response to events.

rds port

AWS RDS Port

Posted on July 6, 2020 | by Rose Zakharia | Leave a Comment

RDS Port

What is an RDS Port?

Open ports:

RDS Port – RDS Port Firewall

They are the TCP/IP port that your database listens on.

Certain companies have a firewall which may directly block connections to the default port for your chosen database engine.

In case you have a company with a firewall which is blocking the default port, you will need to select a different port for your newly specified DB instance.

Upon creating a DB instance which tends to listen on a port that you have specified, you are capable of altering the port through modifying your DB instance.

How does an RDS Port help in Security?

RDS Port – RDS Port Security

If you run your database instances on default ports you will be paving the way for a possible security alert. When the RDS instances ports where your database accepts the connections are moved to non-default ports, additional security will result. Consequently, your publicly accessible AWS RDS databases will be protected from attacks and outer forces.

How to Audit your RDS Port?

The below table shows a list of the endpoint default port that every available RDS database engine has:

Database Engine Name	Default Port Number
Aurora/MySQL/MariaDB	3306
PostgreSQL	5432
Oracle	1521
SQL Server	1433

To determine if your existing RDS database instances are using their default ports, perform the following:

– Using AWS Console –

1 – Sign into the Management Console.

2 – Go straight to the RDS dashboard through the following link https://console.aws.amazon.com/rds/.

3 – Using left navigation panel, from under RDS Dashboard, choose Instances.

4 – Choose which RDS instance you’d like to check.

5 – Select Instance Actions button from the top menu of the dashboard then click on See Details.

6 – From Details tab, under Security and Network section, review the Port number:

RDS Port – RDS Port Number

In case the number turns out to be the default port number for this database engine which is being utilized, then this means that the chosen RDS instance is not operating on a non-default port for connections and this makes it easily capable of being attacked by dictionary and brute force. For the sake of changing the RDS database endpoint port, you will need to go over the following steps that are going to be listed in the section named: “How to Change your default RDS Port?”.

7 – Go over steps numbered 4 and 6 for the sake of verifying the database port for different RDS database instances that are provisioned in the selected region.

8 – Choose a different AWS region using the navigation bar then go over the steps for different regions.

– Using AWS CLI –

1 – Start by running the describe-db-instances command for either UNIX, OSX or Linux through custom query filters for the sake of listing the names of every single RDS database instance that is available in this chosen Region:



12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849

aws rds describe-db-instances

--region us-east-1

--output table

--query 'DBInstances[*].DBInstanceIdentifier'

2 – A table needs to be returned using the command output having the database identifiers that were requested:



12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849

-------------------------

|  DescribeDBInstances  |

+-----------------------+

|  mysql-prod-db        |

|  postgresql-prod-db   |

|  aurora-prod-db       |

+-----------------------+

3 – Once more, run the describe-db-instances command for either UNIX, OSX or Linux through your RDS database instance identifier as well as your custom query filters for the sake of finding the utilized port number which is being used by the chosen resource:



12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849

aws rds describe-db-instances

--region us-east-1

--db-instance-identifier mysql-prod-db

--query 'DBInstances[*].Endpoint.Port'

4 – The port number utilized by your selected RDS instance which is MySQL default port for the example we took, shall be shown through the command output:


12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849

[

3306

]

For example:

– MySQL/Aurora/MariaDB: port 3306

– SQL Server: port 1433

– PostgreSQL: port 5432

– Oracle: port 1521

5 – Go over the step number 3 and that of number 4 in order to review the database port number for different RDS database instances that are being provisioned in this selected region.

6 – Choose a different Region through going ahead and updating the “—region” command parameter value and then going over the step number 1 and step number 5 in order to apply the audit procedure for different AWS Regions.

How to Change your default RDS Port?

To change the default port number for your existing RDS database instances

For the sake of modifying a DB instance and change port settings, follow the steps below:

Login to the Management Console then go straight to the Amazon RDS console using the following link https://console.aws.amazon.com/rds/.
From navigation pane, select section Databases, then click on which DB instance you’d like to modify.
Click on Modify, and the Modify DB Instance page will show up.

RDS Port – Modify Instance Settings for RDS Port

Make changes to whichever settings you’d like to alter.
If you are satisfied with all the changes, click on Continue then review the modifications summary.
You can optionally click on Apply immediately for the sake of directly applying those changes that you’ve made. Sometimes if you select this an outage may possibly occur.
From the confirmation page, go over the changes that you’ve made. In case you accept them and they are perfectly as you need them to be, then select Modify DB Instance for saving the changes.

Otherwise, you can click on Back for the sake of editing the changes or click on Cancel for canceling them.

RDS Port – Change RDS Database Port Number

Console Setting + its Description	CLI Option + RDS API Parameter	When the Change Takes Place	Downtime Notes	DB Engines that are Supported
Console Setting: Database port Description: Which port you’d like to utilize for accessing your DB instance. Its value shouldn’t be the same as that of any one of the port values set for options in the option group which is associated with the DB instance.	CLI option: --db-port-number RDS API parameter: DBPortNumbe	Immediate change. The following setting does not take the apply immediately setting into consideration.	The DB instance gets rebooted right away.	Every single DB engine.

AWS SQL Server Pricing

What is AWS SQL Server?

Amazon RDS has a main building base which is the DB instance. This DB instance is the same as that of the on-premises Microsoft SQL Server. Upon creating an SQL Server DB instance, you will be able to add to it 1 or multiple custom databases.

Keep in Mind

You are capable of creating an SQL Server DB instance, and then connecting to the DB instance and running a simple query. After that you can simply just delete this sample DB instance.

On-Demand AWS SQL Server DB Instances

AWS SQL Server Pricing – AWS SQL Server Direct Connection

AWS SQL Server On-Demand DB Instances allow you to pay the cost of compute capacity for the hour your DB Instance is running free of long-term commitments. This liberates you from the expenses and hardships of arranging, buying, and keeping up equipment and change generally enormous fixed expenses into less variable expenses.

AWS SQL Server Pricing for Single-AZ as well as that for Multi-AZ deployments, is calculated per consumed DB instance-hour, from the start of launching the DB instance till its stop or deletion.

Partial DB instance-hours are charged in 1-second increments with minimum billing of ten minutes following a charged change in status like “starting”, “creating” or “modifying” a DB instance class.

AWS SQL Server Reserved Instances

AWS SQL Server Pricing – AWS SQL Server Meaning

AWS SQL Server Reserved Instances allow you to get a DB instance reserved for a 1- or 3-year term which will get you a great discount in comparison with the On-Demand Instance SQL Server pricing for the same DB instance.

AWS SQL Server offers 3 RI payment options:

– No Upfront

– Partial Upfront

– All Upfront

The above RI payment options give you the ability to keep balance between the amount paid upfront wand the effective price per hour.

AWS SQL Server Reserved Instances offer flexibility in size for the SQL Server database engine. Size flexibility gives the possibility for your RI’s discounted rate to directly be performed on the usage of whichever size in the similar instance family such as T3, M5 and R5.

AWS SQL Server Reserved Instance pricing does not include the I/O or the storage costs.

You are capable of designating AWS SQL Server database instances as Reserved Instance through the call to the Purchasing API or the selection of the Reserved Instance option from the AWS console.

Upon the designation of an AWS SQL Server database instance as a Reserved Instance, you will need to do the following:

– Designate a region (Reserved Instances can be utilized in this designated region only)

– Designate an instance type

– Designate an instance quantity for the applicable Reserved Instances

AWS SQL Server Reserved Instance pricing program is capable of being terminated whenever chosen to.

Along with undergoing Reserved Instance pricing, those Reserved Instances are also subject to every data transfer and different fees that may be applicable.

This article provides a detailed overview of PostgresSQL pricing model, also details the charges incurred per instance types.

AWS PostgreSQL Pricing

Introduction to AWS PostgreSQL Pricing:

In general, AWS PostgreSQL costs nothing when users start with it.
No minimum fee is required. You only pay as you use.
Users can consider Reserved Instances or the On-Demand instances for AWS PostgreSQL.
Cloudysave Pricing Calculator can help you to calculate & estimate your AWS PostgreSQL costs in detail.
AWS PostgreSQL offers a wide list of instance types to choose from, and they are optimized to go with various relational database use cases.

AWS PostgreSQL Pricing for On-Demand DB Instances

AWS PostgreSQL On-Demand DB Instances allow you to pay the cost of compute capacity per hour and these charges will also be discounted based on your DB Instance long-term commitments. This liberates you from other expenses and hardships of arranging, buying & keeping up equipment. This change helps users who are generally paying enormous fixed expenses into less variable expenses.

AWS PostgreSQL pricing for Single-AZ as well as that for Multi-AZ deployments is calculated per consumed DB instance-hour, from the start of launching the DB instance till its stop or deletion.

AWS PostgreSQL Pricing – AWS PostgreSQL Multi-AZ Instance Deployment

AWS PostgreSQL Partial DB instance-hours: calculated per 1-second increments along with a ten-minute minimum charge after a charged status change like starting, modifying or creating a DB instance class.

In the following table, you will provide the AWS PostgreSQL pricing of a DB Instance that is spun up using a Single AZ deployment model. All the charges are considered in US-East-2 (Ohio) region.
