=======
Quality speaks for itself...
SAMPLE QUESTION:
A social gaming startup has its flagship application hosted on a fleet of EC2 servers running behind an Elastic Load Balancer. These servers are part of an Auto Scaling Group. 90% of the users start logging into the system at 6 pm every day and continue till midnight. The engineering team at the startup has observed that there is a significant performance lag during the initial hour from 6 pm to 7 pm. The application is able to function normally thereafter.
As a solutions architect, which of the following steps would you recommend addressing the performance bottleneck during that initial hour of traffic spike?
Configure your Auto Scaling group by creating a scheduled action that kicks-off before 6 pm. This causes the scale-out to happen even before peak traffic kicks in at 6 pm
Configure your Auto Scaling group by creating a lifecycle hook that kicks-off before 6 pm. This causes the scale-out to happen even before peak traffic kicks in at 6 pm.
Configure your Auto Scaling group by creating a target tracking policy. This causes the scale-out to happen even before peak traffic kicks in at 6 pm.
Configure your Auto Scaling group by creating a step scaling policy. This causes the scale-out to happen even before peak traffic kicks in at 6 pm.

What's your guess? Scroll below for the answer...




















Correct: 1.
The scheduled action tells Amazon EC2 Auto Scaling group to perform a scaling action at specified times. To create a scheduled scaling action, you specify the start time when the scaling action should take effect, and the new minimum, maximum, and desired sizes for the scaling action. The engineering team can create a daily scheduled action to kick-off before 6pm and hence this is the correct option.
Auto Scaling group lifecycle hooks enable you to perform custom actions as the Auto Scaling group launches or terminates instances. For example, you could install or configure software on newly launched instances, or download log files from an instance before it terminates. Lifecycle hooks are not the correct choice for this use-case.
With target tracking scaling policies, you choose a scaling metric and set a target value. Application Auto Scaling creates and manages the CloudWatch alarms that trigger the scaling policy and calculates the scaling adjustment based on the metric and the target value.
With step scaling, you choose scaling metrics and threshold values for the CloudWatch alarms that trigger the scaling process as well as define how your scalable target should be scaled when a threshold is in breach for a specified number of evaluation periods.
Both the target tracking as well as step scaling policies entail a lag wherein the instances will be provisioned only when the underlying CloudWatch alarms go off. Therefore we would still see performance lag during some part of the initial hour.
=======

Welcome to the best practice exams to help you prepare for your AWS Certified Solutions Architect Associate exam.
You can retake the exams as many times as you want
This is a huge original question bank
You get support from instructors if you have questions

php-for-beginners

Description
Are you wanting to get into Web development, but are not sure where to start? 

So maybe you tried out some PHP and MySQL tutorials on Youtube, but found them too hard or outdated, and feel that you need a more comprehensive introduction.

Maybe you want to learn how to write PHP the right way.  Secure code, OOP ready, and maximising re-usability as well as finding out about PHP programming standards to adopt and adhere too?

Perhaps your boss or client threw you in the deep end with a PHP and MySQL project, and you need to get up to speed with PHP, fast.

Whatever the reason, this course is for you.

This course is going to teach you how to create web applications using PHP and MySQL.  Specifically, you will learn PHP and then create you own content management system (CMS) from scratch.

Why PHP?

PHP is the most popular website programming language in the world.  The combination of PHP and MySQL is used extensively to create web applications, and developers with these key skills are in high demand.  This course is going to teach you how to create web applications in PHP using the MySQL database.

What will you learn in this course?

You will learn  how to create a dynamic website using the most popular website programming language in the world, PHP.

Dave Hollingworth, your instructor will teach you the PHP programming language, and take you through the steps to build a working CMS in PHP and MySQL from scratch.

Along the way, you will learn how to secure your code, how to write reusable, more maintainable code using programming standards, and how to structure your code using object-oriented programming techniques.

Dave will teach you the theory and then put the theory into practice when building the CMS.

You will also learn how to style your site using Bootstrap, how to integrate third-party code into your site, how to store data in a relational database and use this from PHP code, and more.

The course is very thorough, and goes through everything from installing a web server on your own computer, and editor to writing the code to create your web app.  Towards the end of the course you will even learn how to upload the code and make your code live on the internet (very useful if you already have your own Hosting account).  This is not necessary to complete the course though.

In summary, the course will teach you the core skills you need to know to become a productive PHP programmer.

Why this course?

Firstly, Dave has been creating web applications since 1999, when he created his first web application for a major insurance company.  In addition he has been teaching IT for many years.

As a result, you will be learning the best practices from an experienced developer.

Dave will teach you the theory but then show how to put those techniques into practice.  You will start building a CMS application from early on in the course and new techniques and theory are introduced as and when they're needed to build the next part of the CMS.

New code is introduced one word or one line at a time, so you will never get bogged down or overwhelmed.

You will also learn real-world developer skills such as referring to and getting the most out of the documentation. This is an essential skill for developers to learn.

After completing this course, you will have the necessary skills to be able to create your own web applications with PHP and MySQL.

The sooner you sign up for this course, the sooner you will have the skills and knowledge you need to increase your job or consulting opportunities.    PHP developers are in high demand!

Your new job or consulting opportunity awaits!

Why learn a JavaScript course?
The most obvious reason for learning JavaScript is if you have hopes of becoming a web developer. Even if you haven’t got your heart set on a tech career, being proficient in JavaScript will enable you to build websites from scratch—a pretty useful skill to have in today’s job market!

1) JavaScript experts are versatile - JavaScript is an extremely versatile language. Once you’ve mastered JavaScript, the possibilities are endless: you can code on the client-side (frontend) using Angular and on the server-side (backend) using Node.js. You can also develop web, mobile, and desktop apps using React, React Native, and Electron, and you can even get involved in machine learning.
2) JavaScript experts are in-demand (and well-paid) - JavaScript is the most popular programming language in the world, so it’s no wonder that JavaScript is one of the most sought-after skills in the web development industry today. The global demand for JavaScript seems to outweigh the expertise available on the market. According to this HackerRank report, 48% of employers worldwide need developers with JavaScript skills, while only 42% of student developers claim to be proficient in JavaScript.
3) JavaScript is beginner-friendly - Compared to many other programming languages, JavaScript offers one of the more beginner-friendly entry points into the world of coding. The great thing about JavaScript is that it comes installed on every modern web browser—there’s no need to set up any kind of development environment, which means you can start coding with JavaScript right away!

Another advantage of learning JavaScript as your first programming language is that you get instant feedback; with a minimal amount of JavaScript code, you’ll immediately see visible results. There’s also a huge JavaScript community on sites like Stack Overflow, so you’ll find plenty of support as you learn. Not only is JavaScript beginner-friendly; it will also set you up with some extremely valuable transferable skills. JavaScript supports object-oriented, functional, and imperative styles of programming—skills that can be transferred to any new language you might learn later on, such as Python, Java, or C++. JavaScript provides a crucial introduction to key principles and practices that you’ll take with you throughout your career as a developer.

Download ARONE app database from Vuforia and activate it inside Unity  
Build this app for Android & Ios  
Augmented Reality Book (ARBOOK) application  
In the ARBook application we will first create few sketches inches a drawing book. Next we will download some 3D Models from the asset store and project the 3D Model on top of each image target.  
Application like ARBOOK can be implemented in Schools & Colleges for teaching complicated subjects in a fun and easier way.  
Virtual Button & Augmented Reality Business Card (ARBusinessCard) 
In this section I will explain first explain you the concept of Virtual Button in Vuforia and the six important factors that should be considered while working with Virtual Button.  
Next you will create a simple Virtual Button app called AugmentedRealityVirtualButton in which you will understand the important function & interface that are required for working with Virtual Button.  
After the ARVirtualButton app we will then create and ARBusinessCard. In the ARBusinessCard app you will first place multiple virtual buttons on top of an Image Target. Next I will show you how to play video file inside Unity, After this we will write a C# script to play a particular video when the virtual button for a particular video is pressed  
Augmented Reality Greeting Card
In this section, you will learn the process of detecting multiple image targets simultaneously at the same time. You will also add an mp3 file in the app that will start playing only when the greeting card is opened.

Superimposition based AR | Object tracking –
In this section you will first scan a 3D model using Vuforia’s 3D scanning android application. Next we will import this model inside Unity and on top of this model we will superimpose a digital car.

Cylindrical Object tracking
In this section you will learn the technique for detecting a cylindrical object. After detecting the cylindrical object you will create a beautiful 3D scenic view around the cylinder with the help of airplanes, low poly clouds and low poly terrains.

Vuforia Cloud Recognition
In this section you will understand the working of Vuforia cloud databases. You will create an application called BookInfoAR. This application will scan a book cover(marker) and display information panel beside the book cover. The information of the marker is stored in cloud database.

Ground Planes and MidAir
In this section you will create your first markerless augmented reality using Vuforia Ground Plane. With ground plane feature we will place a lifesize Lamborghini model in real world. Next using the MidAir feature we will place a drone in mid air.

User Defined Target
In this section you will understand a feature called User Defined Target feature from the Vuforia Core Sample. With the help of User Defined Target feature we can use any image as an marker.
So after explaining you the course content I hope to see you inside this Augmented Reality course
