Firebird refers to an open-source SQL Relational Database Management System that runs on Microsoft Windows, Linux, macOS, and various other UNIX platforms.
Features:
SQL Compliance: Firebird adheres to entry-level SQL-92 requirements and the Firebird server supports the development of dynamic SQL client applications. Also, it ships with a host-language precompiler and in-engine language support for embedded SQL development in host languages like C/C++ and COBOL.
Multi-user Database Access: The key objective of Firebird is to give access to a single database to many clients at the same time. In this way, client applications can have active connections to multiple databases simultaneously. Firebird does the work of protection of cross-database transactions through a two-phase commit mechanism. Triggers and stored procedures can post-event messages to interested clients of particular events in the database.
User-Defined Functions: User-defined functions (UDF) can be written and easily stored on the server machine in external shared object libraries. The UDF is available to any client application accessing the database once it is declared to a Firebird database as an external function as if it were a native function of the SQL language.
Security: Firebird maintains a security database storing encrypted passwords and user names. It is situated in the root directory of the server installation and controls access to the server itself and all databases in its physical domain.
It will take a few minutes for your VM to be deployed. When the deployment is finished, move on to the next section.
Connect to virtual machine
Create an SSH connection with the VM.
bashCopy
ssh azureuser@10.111.12.123
Usage/Deployment Instructions
Step 1: Access Firebird from Azure Marketplace and click ON Get it now button.
Click on continue
Now click on create
Step 2: Now to create a virtual machine, enter or select appropriate values for zone, machine type, resource group and so on as per your choice.
Step 4: Open putty and connect with your machine.
Step 5: Login with user name “”
Step 6:- sudo su
Step 7:- Now we can start creating new databases and tables.
# sudo isql=fb
Step 8:- And then, we proceed to create the new database with the following syntax:
:>create database [“database_path.fdb”] user [‘user’]password ‘[password]’;
For eg:-
:> create database “/var/lib/firebird/3.0/data/first_database.fdb” user ‘SYSDBA’ password ‘Niles@123’;
Step 6:- Then, to use it or rather to connect to it we use this other command:
connect “/var/lib/firebird/3.0/data/first_database.fdb” user ‘SYSDBA’ password ‘Niles@123’;
Finally, you can show the installed version:
Until now, small developers did not have the capital to acquire massive compute resources and ensure they had the capacity they needed to handle unexpected spikes in load. Amazon EC2 enables any developer to leverage Amazon’s own benefits of massive scale with no up-front investment or performance compromises. Developers are now free to innovate knowing that no matter how successful their businesses become, it will be inexpensive and simple to ensure they have the compute capacity they need to meet their business requirements.
The “Elastic” nature of the service allows developers to instantly scale to meet spikes in traffic or demand. When computing requirements unexpectedly change (up or down), Amazon EC2 can instantly respond, meaning that developers have the ability to control how many resources are in use at any given point in time. In contrast, traditional hosting services generally provide a fixed number of resources for a fixed amount of time, meaning that users have a limited ability to easily respond when their usage is rapidly changing, unpredictable, or is known to experience large peaks at various intervals.
Traditional hosting services generally provide a pre-configured resource for a fixed amount of time and at a predetermined cost. Amazon EC2 differs fundamentally in the flexibility, control and significant cost savings it offers developers, allowing them to treat Amazon EC2 as their own personal data center with the benefit of Amazon.com’s robust infrastructure.

Secondly, many hosting services don’t provide full control over the compute resources being provided. Using Amazon EC2, developers can choose not only to initiate or shut down instances at any time, they can completely customize the configuration of their instances to suit their needs – and change it at any time. Most hosting services cater more towards groups of users with similar system requirements, and so offer limited ability to change these.
Finally, with Amazon EC2 developers enjoy the benefit of paying only for their actual resource consumption – and at very low rates. Most hosting services require users to pay a fixed, up-front fee irrespective of their actual computing power used, and so users risk overbuying resources to compensate for the inability to quickly scale up resources within a short time frame.
No. You do not need an Elastic IP address for all your instances. By default, every instance comes with a private IP address and an internet routable public IP address. The private address is associated exclusively with the instance and is only returned to Amazon EC2 when the instance is stopped or terminated. The public address is associated exclusively with the instance until it is stopped, terminated or replaced with an Elastic IP address. These IP addresses should be adequate for many applications where you do not need a long lived internet routable end point. Compute clusters, web crawling, and backend services are all examples of applications that typically do not require Elastic IP addresses.
You have complete control over the visibility of your systems. The Amazon EC2 security systems allow you to place your running instances into arbitrary groups of your choice. Using the web services interface, you can then specify which groups may communicate with which other groups, and also which IP subnets on the Internet may talk to which groups. This allows you to control access to your instances in our highly dynamic environment. Of course, you should also secure your instance as you would any other server.
