Now all your network traffic is passing through the proxy and it can alter it:

  • It can replace the User Agent string with some meaningless string or strip out the referrers.
  • It can accept all cookies, but not pass them to you, or it can block them altogether.
  • It’s the proxy that’s connecting to the server, not you, so your IP isn’t disclosed.
  • A proxy can be set up to work system-wide, so programs won’t be able to bypass it.

There are also some extra features that a proxy can provide:

  • It can compress your traffic to save some bandwidth.
  • It can cache files to give a little boost to page load times.
  • It can strip ads from websites before they reach your computer.
  • It can block malicious websites.

And finally, it can be used not only against filters, but also as a filter!

    Technology has been increasingly used  throughout the world. This is very apparent in classrooms today.It is disagreed that technology will replace the teachers in class room.

    This will be proved by analyzing how teachers can crater to the needs of their students as well as motivate and discipline them.A very important aspect of teaching is ability of the teacher to shape their teaching style to the needs of their students.
As an example, If students in any give class are having trouble understanding a classroom topic, a teacher can rephrase the topic and deliver it in more effective way.

    A computerized teacher would be less in-tune with what students require and thus would be incapable of doing this.
Thus, technology will not replace teachers.Motivation and disciple are key to student’s academic success in class room.
This is very apparent, when teaching children as children require more motivation and discipline to be taught effectively.Technology based teacher simply cannot accomplish this as certain situations demands judgement as to whether the student is acting in appropriate manner.

    After analyzing, it is clear that the teachers will always be needed in the classroom.
Following the analyzation of the teacher’s ability to crater the students as well as their capability of guiding towards success,.
it is clear that technology will never replace teachers and class room
It is expected that , technology will act as a supplement to teachers.

SOLID Principles

SOLID

Single Responsibility Principle
       There should never be more than one reason for a class to change.

Open Closed Principle
       Module should be open for extension but closed for modification.
      Eg: For existing 10 algorithm, if I have to add 11th algorithm it should allow for extension.

Liskov Substitution Principle
    Functions which uses reference of base class, should be able to use objects of derived class without knowing them.
    Eg: Program generic Interface, and do not refer concrete classes.

Interface Segregation Principle
    Many client interface are better than one generic Interface.

Dependency Inversion Principle
High level modules should not depend on low level modules. Do not depend on many classes, depend on Interfaces or abstractions.
Both should depend on abstractions.
Abstractions should not depend on details.
Details should depend on details.
Program to interface, not to concrete classes.

Fundamentals in OOPS Concepts


Oops Concepts
Abstraction
   focusing on essential characteristics of an object not all.
Encapsulation
   which hides internal details of object.
Modularity
    dividing cohesive and loosely coupled
  
Hierarchy
    (is a)
   (part of) – Aggregation
                       Containment
Aggregation(diamond)
   Inner objects life-time is not controlled by outer object.
Containment
    Inner objects life-time is controlled by outer object.
Polymorphism ( can be Aggregation
    compile
    runtime
Namespace
    Logical naming and grouping

Inheritance:
    It is white-box reusability. Concrete class can easily override the logic in base class.

Composition:
  It is black-box resuse, when I am using the object, I get access its public property but not its private.

Design Patterns (Brief)

9Design Patterns

What is Software Architecture?


* Architecture Is a Set of Software Structures
3 categories of architectural structures:

                                              Fig23
Technorati Tags:

1. Modules. ( Module structures are static structures)
modules
2. Component-and-Connector (components are runtime entity).
                                               cc
3. Allocation Structures  (mapping of Software structures to environments like organizational, developmental, installations and execution)

REST architectural style describes six constraints applied to architecture

 

1. Uniform Interface

uniforminterface uniforminterface2
Individual resources are identified using URLS. The resources (database) are themselves different from the representation (XML, JSON, HTML) sent to the client. The client can manipulate the resource through the representations provided they have the permissions. Each message sent between the client and the server is self-descriptive and includes enough information to describe how it is to be processed. The hypermedia that is hyperlinks and hypertext act as the engine for state transfer.

2. Stateless Interactions

stateless
none of the clients context is to be stored on the server side between the request. All of the information necessary to service the request is contained in the URL, query parameters, body or headers.

3. Cacheable

restcache
Clients can cache the responses. The responses must define themselves as cacheable or not to
prevent the client from sending the inappropriate data in response to further requests.

4. Client-Server


The clients and the server are separated from each other thus the client is not concerned with the data storage thus the portability of the client code is improved while on the server side the server is not concerned with the client interference thus the server is simpler and easy to scale.

5. Layered System

layered
At any time client cannot tell if it is connected to the end server or to an intermediate. The  intermediate layer helps to enforce the security policies and improve the system scalability by enabling load-balancing

6. Code on Demand

restcodeondemand

Technorati Tags:

an optional constraint where the server temporarily extends the functionality of a client by the transfer of executable code.

Web API Best Practices

 

Considering Top 10 Status

200 – OK – Everything is working
201 – OK – New resource has been created
204 – OK – The resource was successfully deleted

304 – Not Modified – The client can use cached data

400 – Bad Request – The request was invalid or cannot be served. The exact error should be explained in the error payload. E.g. „The JSON is not valid“
401 – Unauthorized – The request requires an user authentication
403 – Forbidden – The server understood the request, but is refusing it or the access is not allowed.
404 – Not found – There is no resource behind the URI.
422 – Unprocessable Entity – Should be used if the server cannot process the entity, e.g. if an image cannot be formatted or mandatory fields are missing in the payload.

500 – Internal Server Error – API developers should avoid this error. If an error occurs in the global catch blog, the stracktrace should be logged and not returned as response.

Explain Elastic Block Storage? What type of performance can you expect? How do you back it up? How do you improve performance?

 How do you improve performance?
EBS is a virtualized SAN or storage area network.  That means it is RAID storage to start with so it’s redundant and fault tolerant.  If disks die in that RAID you don’t lose data.  Great!  It is also virtualized, so you can provision and allocate storage, and attach it to your server with various API calls.  No calling the storage expert and asking him or her to run specialized commands from the hardware vendor.



Performance on EBS can exhibit variability.  That is it can go above the SLA performance level, then drop below it.  The SLA provides you with an average disk I/O rate you can expect.  This can frustrate some folks especially performance experts who expect reliable and consistent disk throughput on a server.  Traditional physically hosted servers behave that way.  Virtual AWS instances do not.

Backup EBS volumes by using the snapshot facility via API call or via a GUI interface like elasticfox.

Improve performance by using Linux software raid and striping across four volumes.

What is S3? What is it used for? Should encryption be used?

S3 stands for Simple Storage Service.  You can think of it like ftp storage, where you can move files to and from there, but not mount it like a filesystem.  AWS automatically puts your snapshots there, as well as AMIs there.  Encryption should be considered for sensitive data, as S3 is a proprietary technology developed by Amazon themselves, and as yet unproven vis-a-vis a security standpoint.




More references on AWS S3 here

What is an AMI? How do I build one?

AMI stands for Amazon Machine Image.  It is effectively a snapshot of the root filesystem.  Commodity hardware servers have a bios that points the the master boot record of the first block on a disk.  A disk image though can sit anywhere physically on a disk, so Linux can boot from an arbitrary location on the EBS storage network.

Creating Base AMI

  







Build a new AMI by first spinning up and instance from a trusted AMI.  Then adding packages and components as required.  Be wary of putting sensitive data onto an AMI.  For instance your access credentials should be added to an instance after spinup.  With a database, mount an outside volume that holds your MySQL data after spinup as well.

How to vertically scale an Amazon instance?

Yes.  This is an incredible feature of AWS and cloud virtualization.  Spinup a new larger instance than the one you are currently running.  Pause that instance and detach the root ebs volume from this server and discard.  Then stop your live instance, detach its root volume.  Note the unique device ID and attach that root volume to your new server.   And the start it again.  Voila you have scaled vertically in-place!!

Types of Scaling



What is auto-scaling? How does it work?

Autoscaling is a feature of AWS which allows you to configure and automatically provision and spinup new instances without the need for your intervention.  You do this by setting thresholds and metrics to monitor.  When those thresholds are crossed a new instance of your choosing will be spun up, configured, and rolled into the load balancer pool.  Voila you’ve scaled horizontally without any operator intervention!



With MySQL databases autoscaling can get a little dicey, so we wrote a guide to autoscaling MySQL on amazon EC2.



What automation tools can I use to spinup servers?

The most obvious way is to roll-your-own scripts, and use the AWS API tools.  Such scripts could be written in bash, perl or other language or your choice.  Next option is to use a configuration management and provisioning tool like puppet or better it’s successor Opscode Chef.  You might also look towards a tool like Scalr.  Lastly you can go with a managed solution such as Rightscale.

TOP AWS Interview Questions

What is configuration management? Why would I want to use it with cloud provisioning of resources?


Configuration management has been around for a long time in web operations and systems administration.  Yet the cultural popularity of it has been limited.  Most systems administrators configure machines as software was developed before version control – that is manually making changes on servers.  Each server can then and usually is slightly different.  Troubleshooting though is straightforward as you login to the box and operate on it directly.  Configuration management brings a large automation tool into the picture, managing servers like strings of a puppet.  This forces standardization, best practices, and reproducibility as all configs are versioned and managed.  It also introduces a new way of working which is the biggest hurdle to its adoption.




Enter the cloud, and configuration management becomes even more critical.  That’s because virtual servers such as amazons EC2 instances are much less reliable than physical ones.  You absolutely need a mechanism to rebuild them as-is at any moment.  This pushes best practices like automation, reproducibility and disaster recovery into center stage.

Explain how you would simulate perimeter security using Amazon Web Services model?

Traditional perimeter security that we’re already familiar with using firewalls and so forth is not supported in the Amazon EC2 world.  AWS supports security groups.  One can create a security group for a jump box with ssh access – only port 22 open.  From there a webserver group and database group are created.  The webserver group allows 80 and 443 from the world, but port 22 *only* from the jump box group.  Further the database group allows port 3306 from the webserver group and port 22 from the jump box group.  Add any machines to the webserver group and they can all hit the database.  No one from the world can, and no one can directly ssh to any of your boxes.

How to pass JS variable value from View to Controller

One of the easiest approach to handle this problem is

1. Add a new property into your Model.
2. Create a hidden input control in view , which maps to the newly created property of your Model.
3. Update the value of your hidden control in js function.

Let do it...

1.  Model
        public class Model: GenericEntityPoco
    {
           // your property
        [HiddenInput(DisplayValue = false)]
        public DateTime FromTime { get; set; }
    }


2.   In the view ( Create View)
          @Html.HiddenFor(model => model.FromTime)
          <input type="submit" value="Create" class="btn btn-primary btn-lg" onclick="setSlotSelected();" />

3. JS
    function setHiddenControl()
    {
        document.getElementById('FromTime').value = "myValue to be updated";
        return true;
    }
