How can we understand Django?

Hello, my loving friends, today in this article. We are going to deliver a brief description of Django. In this course details, we are covering the prominent part of Django for beginners. If you are a python learner or a seeker then this is the exact place for any individual those have been looking for. In this topic, we have covered all the beneficiary subjects regarding this course. I will really say that this will give you the best experiences of your doing and what you are going to do.

What is Django?

Django

Django is a free and open-source web framework. Now you will say it is ok we don’t know about the free part and its open-source part but what is a framework? Now. The framework is a combination of certain components and packages. Definitely, if you want to build some complex application. There are certain things that you need to make. For example, if you want to make a web application. You don’t want anything from scratch. It will be time-consuming. So, you will be using a framework here. Now, Django is not the only framework that’s only available.            

Why use the Django framework?

Django framework

One of them is and one of the famous ones is Django. Why do we have to learn Django there? Django as we know is a web application framework that means you can build web applications. But hold on, our websites are so important definitely. If you talk about any business, they need their own online presence. In fact, most of the virtual solutions which you use nowadays are web applications. For example, if you want to buy something online, we have amazon, flip kart, and eBay. If you want to book a cab, you have an uber. We have so many applications available which are based on the web. If you want to build them, you will be using Django there. But you talk about the websites, we know that you can build websites with the help of HTML, CSS, & JavaScript. So, basically, we use HTML to design the page. You can think of HTML as makeup for you. Now that you have CSS, if you want to improve your design, if you want to have that uniformity in the design that’s you will use CSS. We have Html, CSS for design. To make your websites interactive, you can use JavaScript.

Static and dynamic website

Yes, you use HTML, CSS, and JavaScript in the front hand. What about the backhand part? What if you want to make a website like a dynamic website? For example, if you go to Facebook, everyone will get influent by the feeds, you will not see the same messages which everyone is seeing. Your Facebook is different from that. If you go to amazon, you can buy stuff online, you can pay, and you can transfer the amount online. All these things need certain operations and certain processing is done on the backhand side. That’s where we need a line base that will work on the backhand but which one? But we have certain options there, we have java using, if you have heard about servlet, you can do that, PHP, Asp, and Python. But hold on, how can you do that python?          

How Django can be used?

That’s where we have Django. So, you can use Django to build a web application in the backhand part in python. As I mentioned before, Django is not the only web framework is available but it’s quite famous there. Now, it comes to web applications one thing that is very famous in MVC. It doesn’t matter which language you learn maybe java, PHP, or asp. We have this thing common in MVC (Model view controller). Now. Basically, we do that you can separate the concerns. We have a model for data, view the Html format that you have seen on the screen and then we have a controller which will control these operations.          

What is MVT in Django?

But in general, when you say MVC, it will help you to build a good web application but in Django, we have something similar to MVC not exactly MVC normally call as MVT. So, MVT is a model view template so basically in MVT we are replacing the controller with a view and replacing the view with the template. But Django basically follows MVT so, if you have worked on MVC in a different language. Don’t worry, it’s almost the same but needs some changes. But why did you choose Django? When you have some other framework is available in python. The first Reason is Django is fast, which simply means if you want to build something, you shouldn’t be spending much time in the configuration so, Django will help you to build applications faster. The second one is the number of components available.

The thing apart from if you record a video, you need some components with you. You need a camera, lights, and mike, in the same way, if you want to build a web application. You need log in, database connectivity, all these things come bundled in Django. Does advantages and drawbacks as well, advantages you have everything with you and drawback, you have everything on you. The third one is security if you are building an application where you use it. Definitely, there will be sending the data and you want to secure them & the users. So, Django will provide you with that security. The fourth one is scalability, what if in future sites scales, you want to have multiple users, & more features and it will give you the options as well. That’s the reason, you should be learning Django. It is interesting so if you have done your python course. This is the very true place and accurate learning path for you.

5 Keys to Automating Configuration Management for Application Infrastructure

One of the trends being discussed in business, among vendors and in the analyst community is the importance of automating the functions performed by IT. Growing demands by the business, tight budgets and compliance pressures together accentuate the need for IT to be more agile, efficient and responsive to business stakeholders.

Naturally, vendors rush into this environment, each touting the unique benefits of its solution set and the urgency to move forward immediately.  A key area targeted for IT automation is the area of ‘configuration management.’  As it relates to automating day to day IT functions, configuration management can mean many different things: patch management, server and network management or others.

Can’t connect to the application server

scmuser created the topic: Can’t connect to the application server

Symptom: The application the user is trying to open may alert that it cannot connect to the application server. This can be the case when using e-mail applications or CRM Applications. The common complaint into the help desk is that the network is down,
even though this is not the true problem.

sgadmin replied the topic: Re:Can’t connect to the application server
Cause: Several things can cause this event. The key question to ask the user is whether this problem happens constantly or only sporadically. If the user has a proper IP address for the connection they are on, there may be a routing issue on the network between the user and server. This can be verified with a simple ping. If connectivity is lost sporadically, this can be caused by a busy server that is not responsive to client requests.
Resolution: In the case that routing is not the issue (ping test), check the server load and resources. Is the server busy running another task such as a backup? If this is not the case, check the network load between client and server, focusing on WAN connections if there are any. Often, periods of high network utilization between client and server can cause connectivity problems for the client. The best way to do this is by using an SNMP tool that will monitor utilization over time on these links. Additionally, look for Ethernet Errors on all switches and routers that cause packet loss between client and server.

Slow application performance

scmuser created the topic: Slow application performance

Symptom: The application appears sluggish. It may freeze on a certain screen or halt while accessing data. Often, the network is blamed for these issues.

sgadmin replied the topic: Re:Slow application performance

Cause: Exonerating the network in application performance problems can assist server maintenance personnel to take out the guesswork and isolate the issue to the right place. Many issues can cause an application to slow down. Among the most common causes are server backups occurring during production hours, slow response from database servers, and packet loss on the network. From a network technician’s point of view, the most important thing to determine is whether the problem is caused by the server or by the network. To determine this, a capture of application traffic can be collected from a client machine. Look for any retransmissions between the client and server. If retransmissions exist, there is packet loss on the network, which severely affects application performance. If there are no retransmissions and connectivity between client and server is established, the problem is likely in the server and can be monitored from that perspective.
Resolution: Although packet analyzers can be very difficult to use when tracking down a problem, they often are equipped with simple counters displaying TCP retransmissions. Use this counter to assist in determining if there is packet loss on the network between client and server. Look for Ethernet errors (FCS Errors, Alignment Errors, or Late Collisions) on any switches and routers between client and server that could be causing this packet loss. If there are no errors, watch for packet loss on the WAN because of excessive utilization across the link.

Apache Tomcat – Tomcat 7 Finalized – Tomcat 7 Introduction

tomcat-7

The volunteer developers behind Apache Tomcat have released version 7.0.6 of the open-source Java servlet container.

“This is the first stable release of the Tomcat 7 branch,” developer Mark Thomas wrote in an e-mail announcing the release on various Tomcat developer mailing lists.

While not a full application server, Tomcat implements the functionality described in the Java Enterprise Edition Web profile specifications. Most notably, it supports version 3.0 of the Servlet API (application programming interface) and version 2.2 of JavaServer Pages, both part of the recently ratified JEE 6. A servlet container manages Java-based applications that can be accessed from a Web browser.

The use of Servlet 3.0 will bring a lot of new capabilities to Tomcat, noted Tomcat contributor Tim Funk, in a presentation at the ApacheCon conference in Atlanta in November.

One big area of improvement is in configuration management for Web applications. Previous versions required all Web app configuration changes to be entered in a central file called web.xml, a process that led to unwieldy web.xml files as well as security risks.

The new approach, called annotations, breaks configuration instructions into multiple files. Separate files are kept for security, for configuring new connections, for initial parameters and for handling third-party libraries.

Other benefits of Servlet 3.0 include advanced cookie management and asynchronous thread support, which should increase the number of connections Tomcat can handle.

In preparation for the release, various beta versions of Tomcat 7 have been distributed since April 2010. Version 7.0.6 fixes some longtime memory leak issues and includes a number of other bug fixes as well.

In addition to making the source code and various binaries available, the development team has packaged a version of the software that can be embedded in other applications.

Tomcat is one of almost 150 open-source projects maintained by the Apache Software Foundation.
