DOCKER

1) we can make a container with the required setup.  container is nothing but the isolated environment for running the application. Virutal machine vs container:  Hypervisors -- we can manage virtual machine.  dis : Each VM needs a full-blown OS     slow to start Resourse intensive.   Containers : adv : allow multipel apps in isolation   are lightwegiht use OS of the host start quickly need less resources. DOCKER Architecutre: client server architecture.(REST APIs) All the containers shares the same OS. INSTALLING : download from docker hub. docker version -- both for client and server will come. DEV WORKFLOW : 1) take application and add dockerfile to convert into docker application. 2) turns into image by docker. 3) container gets created based on the application needs. 4) we can push the image to docker registry. so that we can use the image from registry to any test/production environment. 5) Docker registry is nothing but like github for docker.

RDBMS vs NOSQL

-

 RDBMS :          RDBMS stands for Relational Database Management System, example of this RDBMS is mysql, postgresql etc., this database systems is build primarily on relations between tables as of primary key and foreign key. The tables  in this databases are with fixed schema as per we cannot change the no of columns when our application scales up. when you want to use the application for the Transaction involved then RDBMS is the way to go. The primary selling point of the RDBMS is the Transaction.      when we try to scale our application, we can use 2 methods namely  Vertical Scaling Horizontal Scaling  Limitations of Scaling with RDBMS :      When the data is present in only one server, then the scaling in RDBMS is also good but when the application grows we need multiple servers to  store the data, while calling that because of the network I/O and the join statements is  usually a costly query to run. While combining with the other servers it makes the query very slow. That is w

Converting ids into order id in join statement.

  convering id into order_id from mysql in join     I faced a task to show orderId from normal primary key id in mysql DB. I am working on Node js on backend the orderId is the one I need  to send to frontend to display in alphanumeric type. ( eg : SPK00020, SPK00023) 20 and 23 being the primary key of the table in mysql. Approach :            I researched about the ways to generate random number and concat it with the id and lot of ways to do in backend itself but that didn't turn out to be a optimal approach.      After lot of reasearch I finally found a way to generate order id from mysql itself in the same statement I need to use the join statement itself.  LPAD method :  syntax :  LPAD(str,len,padstr); SELECT LPAD(7, 3, 0); +---------------+ | LPAD(7, 3, 0) | +---------------+  | 007 | we can use non-zero values also in this method. SELECT LPAD(7, 10, '.');     +------------------+ | LPAD(7, 10, '.') | +------------------+ | .........7 | +------

Launching AWS hosting services.

Hoisting SAAS code from AWS single cloud storage for multiple users     Steps to upload source codes to aws :   We have to choose the required container for our application based on the use cases to upload the source codes. Then we have to make that source code public to all the other applications that are running on our AWS account within the same region. This S3 bucket can be used for more static sides of the application we are launching( images, blogs, videos) which we can be rendered fast from these buckets. Steps to start a instance using AWS:   Instances are nothing but virtual servers that we can use to run our application. These servers are configurable based on our needs. Scalable, Reliable and cost effective as we only have to pay as we use. We can setup the server with the required configurations for CPUs and storage needs from AWS EC2. We have to create instances in the same region as the codes are stored in a bucket. While creating an instance, we will have
