let's review the functionality provided by Docker. first, let's execute docker PS command as you may recall Dr. PS command only shows the running containers by Default. which is why right now we can see no container is running on our System. when you want to run a container you will need to have some container images. beforehand let's inspect what images are available to us on our system to do this .we will advocate docker. images command to display all the existing images and here it lists out the images we have downloaded already apart from images already available. You can also pull more images from the Internet let us show you how to do this. we are going to try and download something lightweight there is a lightweight operating system called busy box combines tiny versions of many common UNIX utilities into a  small executable. it provides replacements for most of the utilities you usually find in GNU file utils Shell utils etcetera the utilities in busy box generally have fewer options than their full-featured GNU cousins however the options that are included provide. the expected functionality and behave very much like their GNU counterparts busy box provides a fairly complete environment for any small or embedded system it is a quite a popular image to test out docker functionality. what we are going to do is that will execute docker search busy box command what this command does is it goes out to the internet and searches for all the container images which match the name busy box. here is the search result for the images available freely and publicly we will discuss more about the actual source of these search results. later okay so now we have got the busy box container image we are looking for this is the base image released by docker .there are other images that are customized versions of busy box images modified by other developers according to their needs and shared back to the community.so now that we have found the image we are looking for the next step is to download it on our system for that. we will use a command called docker pull let's execute docker pull busy box to download it so as you can see it has to download this image from the internet but since container images are so compact the process took only a few seconds. now let's execute docker images command to verify that the new image has been downloaded and it is ready for us and voila we can see the basic box image is on the list let's execute another search and this time let's search for send to s here you can see the official sent to s image since docker is so popular and people across the world are customizing and sharing images on public repositories. you can simply search the docker repositories for any particular operating system or package here is every possibility that you will find something relevant and if it doesn't exist or doesn't match your exact requirements. you can download the closest match customize it and share it back with the community you can easily look for images for popular packages like Apache my sequel back stack OpenStack Tomcat etc. all these popular packages are readily available in the public docker repository next functionality that we should discuss is the docker hub. docker hub is a cloud-based registry service it provides a centralized resource for container image discovery distribution and change management user and team collaboration and workflow automation throughout the development. pipeline all the publicly shared docker images are actually stored in this public repository even the docker search command we used earlier basically searches docker hub repository for available images the URL for docker hub is hub docker com. let's visit docker hub and explore it alright so here is docker hub this is the web-based interface to the public repository here also you can perform a search for a  rocker image, for instance, let's search for busy box you can see it returns familiar search results which were found in the terminal window as well which proves that the

 AWS Tutorial For Beginners

Introducing AWS IOT

AWS IOT could be a platform that allows you to attach devices to AWS Services and different devices, secure information and interactions, method and influence device information, and change applications to interact with devices even when they are offline

-AWS is easily and securely connect devices to the cloud.

-It is fast, easy to use and cloud powered business intelligence.

Introducing AWS import/export snowball

AWS Import/Export Snowball, a petabyte-scale data transport solution that uses secure appliances to transfer large amounts of data into and out of AWS. Using Snowball addresses common challenges with large-scale information transfers as well as high network prices, long transfer times, and security issues.

Transferring data with Snowball is simple, fast, secure, and can be as little as one-fifth the cost of high-speed Internet.

-It is quick, secure,petabyte-scale information transport answer.-This is totally different; don't get confused with amazon e-commerce half.

IOT

The Internet of Things (IOT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

Amazon invested highly in IOT.

EC2

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers.

-It is a virtual server in the cloud.-On EC2 dashboard select region.-Amazon services are region based.-If you click on any region you will find the window opening in that interest.

To start using amazon EC2 you need to launch a virtual server known as amazon EC2 instance.

On dashboard click launch and window will come up with step 1.

Step 1- Quick start

AMI

An Amazon Machine Image (AMI) provides the data needed to launch AN instance, that may be a virtual server within the cloud. You specify an AMI when you launch an instance, and you can launch as many instances from the AMI as you need. You can additionally launch instances from as many alternative AMIs as you wish.

-These are the different default images.

AWS Market place

AWS Marketplace is an online store where you can sell or buy software that runs on Amazon Web Services (AWS). AWS Marketplace enhances programs like Amazon DevPay and therefore the Amazon Partner Network.

« Back

 Find and buy software that runs in the AWS Cloud software from trusted vendors like Sap, zend, Microsoft as well as many open source offerings. You can now find and launch software directly within EC2 for all AWS marketplace AMI products.

This software is available in the form of Amazon Machine Images (AMIs).

Docker Tutorial for Beginners

Docker has become one of the biggest and the most popular software container platform. Packing your code into small containers that would run on any environment regardless of the OS and architecture made it not only easy to make your code portable but also easier to collaborate with other programmers and developers. Docker made it easy to write and run your code on multiple platforms by wrapping up a piece of software in a complete file system package, installing it on a server, and running it repeatedly, without requiring manual effort. However, Docker became a little difficult to use with micro-architectures that composed of multiple containers working simultaneously, which is why Docker introduced its Docker Compose, a handy tool to have when working with Docker. Docker Compose makes it easier to define and run application environments that includes multiple Docker containers. Before Compose, running more than one Docker container was complicated, but with Docker, you can now run numerous Docker containers efficiently. If you want to make your Docker process more efficient, then this the perfect course for you to learn Docker Compose!

hey, guys, this is key and I just want to cut this clip video showing my eBay back-office. this is 99.9% drop shipping, okay so here the last 31 days of sales 25,000 we came really close it's a rolling 31 days. We came really close to 50 the other day and did quite crack it but we're not even we're not pushing this. I mean yeah we're listing we list this six days a week but we're not I could easily scale this like to two to three times what we're doing right now. I'm just you know we're buying a house and I have all this other stuff going on but eBay is an excellent income stream um yeah so I don't get the believer in having multiple streams right you should be to my opinion. you can see here we did we get over 3000 that day 27 hours 28 20 21 yesterday. you know you have ups and downs but it is what it is like I said we're not really we're not getting it really really hard. so it's exciting to me you know to see these numbers know that we're not we could do so much more with it and I really need to and we'll you know I want to see this be over six figures every single month that's my Goal, and we will do it we're going to keep pushing until it happens. so drop shipping you have to learn to do it correctly right I'll take a lot of training watched a lot of videos I've spent a lot of money to learn my no and you have to know how to handle customers Right, if you're going to get upset customers whether you're drop shipping or not and the better you can handle them. the better off you're going to be you can see look last 30 days 133 positive on neutral. Whatever um drop shipping you would think you know you have a lot of issues but no we're top rated right now with this. you're supposed to be 90 percent tracking uploaded on time to remain top rated would point one below. So, we'll fix that will be top-rated again next month so yeah I just wanted to cut this quick video do not be intimidated by it but don't try it without the proper you know instructions. that's where people mess up that's what gets gives drop shipping a bad name is people get in there right here you know they make Google a CEO you just have to do just this on this and they go try it and then boom whatever you know these selling out stock irons or they get trouble one way or the other and you can't do that and succeed need a solid foundation to be able to do this successfully . so I just want to cut this quick video show you know what we've got going on here and where we're headed that's it I'm great.

AWS Tutorial

welcome to this module on cloud computing and AWS. in this module, we will talk about the AWS ecosystem its services and how you can implement AWS cloud services for your own needs. In this module, we will introduce you to the concept of cloud computing. in the context of Amazon Web Services, we will see how AWS is conquering the world of applications through the promise of

scalability and sophistication. this is a foundational module the information in this module will help you to understand the basics of cloud computing and why AWS has proven to be the cloud platform

of choice for many companies around the World. in case you are already familiar with AWS and its service offerings then feel free to skip this module and jump right on to the next module in which we

will talk about the Cole topic of this Course. this is an overview of this module about cloud computing and AWS here are the key outcomes you can expect to take away from this module. After completing this module you will be able to understand what cloud computing is and comprehend various benefits cloud computing provides. discover why companies are switching over to cloud computing and in particular to AWS cloud. identify prime AWS users and learn why they are using it .realize how AWS can

help your business and expand it .explore AWS services and learn to run your workloads using these services and apply this knowledge and begin using AWS services for your own needs. alright so

let's get started, let's review the basics first and understand the most important and basic term cloud computing so what is the cloud? computing cloud computing is a general term used for the delivery of hosted services over the Internet. cloud is a broad and deep platform that helps customers build sophisticated scalable applications cloud computing enables companies to consume a computing

resource such as a virtual machine, storage or an application as a utility. just like electricity. rather than having to build and maintain computing infrastructure in-house you can just pay or leave some time on these computer resources and use them for your purposes. next, let's see why companies are switching over to cloud computing and in particular to AWS. traditional methods of hosting and administering IT

infrastructure meant we had to deploy monolithic data centers and physical Servers. the lead time for this heavy infrastructure deployment was few days to few weeks it needed large amounts of capital spending upfront. this model often led to energy wastage low utilization and high efforts for the

administration of hardware servers .it was rather difficult to scale these operations very quickly .whether it was to expand the operation to meet growing demand or to shrink operations due to

reasons like seasonality .cloud is a generic term used for a platform that provides hosting services over a network. at the core of cloud computing is hardware virtualization because of this cloud infrastructure can provide us access to shared pool of computing resources which could be rented or leased on an on-demand basis. some of the main benefits and driving forces behind cloud computing are that cloud computing allows companies to avoid upfront infrastructure costs and focus on projects that differentiate their services and products. in the recent years this has enabled technology start-ups to invent and come up with innovative technologies and products without worrying about spending a lot on

up front fixed infrastructure .cloud computing allows enterprises to get their applications up and running faster with improved manageability and less maintenance .cloud computing enables IT department to rapidly adjust resources to meet fluctuating and unpredictable business demand .major cloud providers

are vastly trying to use renewable energy sources to run their data centers and they are also coming up with more efficient data center designs to reduce energy consumption per unit of computing Resource. this obviously has tremendous advantages for the environment. Since cloud providers can manage their data centers more efficiently and cheaply these savings can be passed on to the cloud consumers. the availability of high capacity networks low-cost computers and storage devices, as well as the widespread adoption of hardware virtualization service-oriented architecture and atomic utility computing, have led to a growth in cloud Computing. companies can scale up as computing needs increase and then scale down again as demands decrease cloud computing has become a highly demanded service or utility due to the advantages of high computing power cheap cost of

services high-performance scalability, accessibility as well as availability .some cloud vendors are experiencing a growth rate of 50% year-over-year which is just astounding. cloud computing can be deployed in multiple configurations the most popular configuration is, of course, a public cloud these cloud services are provided by public cloud provider companies like Amazon, Microsoft, Google, Rackspace etc. any individual or company can pay the appropriate fee and buy the required services from these public cloud Providers. the services are isolated for the individual customers so that there

is no interference with other customers data or compute resources but the cloud consumers do not have any control over the underlying infrastructure and hardware of the cloud resources. When companies need more control over the infrastructure they deploy shareable IT infrastructure in their private data Centers. this provides the facility and convenience of a cloud company to all the consumers within the company at the same time giving more control to the company over their resources, but in many situations, companies need to adopt a hybrid approach, where they make use of both public and private cloud Infrastructure. these two separate segments are joined via a secured network link and the IT resources in both public and private clouds can talk to each other. this configuration is called a

hybrid cloud.
