How to create a Database instance on Cloud? – Databases and SQL for Data Science #3


Hello, and welcome to,
How to create a database instance. After completing this lesson, you will be able to understand basic
concepts related to Cloud databases, database service instance, as well as
demonstrate an example of how to create a service instance on
an IBM Db2 Warehouse on Cloud database. A Cloud database is
a database service built and accessed through a Cloud platform. It serves many of the same functions
as traditional databases with the added flexibility of Cloud computing. Users install software on a Cloud
infrastructure to implement the database. Advantages of using Cloud databases
are ease of use, users can access Cloud databases from virtually anywhere
using a vendors API or web interface. Scalability, Cloud databases can
expand their storage capacities during runtime to accommodate changing needs,
organizations only pay for what they use. Disaster recovery, in the event of
a natural disaster equipment failure or power outage data is kept secure
through backups on remote servers. A few examples of cloud SQL databases
are IBM Db2 Warehouse on Cloud, composed for PostgreSQL, Oracle
Database Cloud, Microsoft Azure Cloud, SQL Database, Amazon Relational Database
Services, which can run in the Cloud, either in a virtual machine or
as a service depending on the vendor. Database services are logical abstractions
for managing workloads in a database. Each service represents a workload
with common attributes, service level thresholds, and priorities. The grouping is based on attributes of
work that might include the application function to be used, the priority of
execution for the application function. The job class to be managed or the data range used in the application
function or job class. An instance of the Cloud database operates
as a service that handles all application requests to work with the data and any of
the databases managed by that instance. The database service instance is
the target of the connection request from applications. The application we will
be using is Python. When a connection has been completed
your Python code sends SQL statements across the connection
to the instance of the database. The database instance then resolves
the SQL statements into operations against the data and objects in the database. Any data retrieved is
returned to the application. Now let’s see how a database instance
is created for Db2 Warehouse on Cloud. IBM Db2 Warehouse on Cloud is a SQL
database provisioned for you in the Cloud. You can use Db2 Warehouse, just as you
would use any database software, but without the overhead and
expense of hardware, setup, or software installation, and maintenance. Among the service plans offered for
Db2 Warehouse, you can use the data warehouse
to store relational data, analyze data using built-in analytics,
or by connecting your own apps. The Db2 Warehouse database can be
provisioned on IBM Cloud and for AWS. Now let’s see how we can set up
a service instance of Db2 Warehouse. Navigate to IBM Cloud and
select the Db2 Warehouse on Cloud service. Type a service instance name,
choose the region to deploy to, as well as an org and space for
the service, then click Create. You can view the IBM Db2 Warehouse
service that you created on your IBM Cloud dashboard. You should be able to see details related
to connection configuration when you open the web console for
the Db2 Warehouse on Cloud service. The connection details include the
following, a host name, which is a unique name or label assigned to any device that
is connected to a specific computer network. A port number, which is the database port, the database name,
which is the database name. A user ID, which is the username
you’ll use to connect, password is the password you’ll use to connect,
the version of DB2 Warehouse on Cloud. Thank you for watching this video.
