Keys to crack interview
We provide Workshop certificate to candidates.
It is very difficult to say YES to a Product of One OEM and No to the Product of another OEM especially in the case where in the OEM’s are of the likes of CISCO or JUNIPER. BOTH ARE EQUALLY COMPETENT AND HAVE THE MATURED LINE OF PRODUCTS.
DEPLOYMENT WISE, JUNIPER IS MOST SUITABLE FOR THE CORE-LAYER OF THE NETWORK WHEREAS CISCO IS MOT INTO THE ACCESS-LAYER OF THE NETWORK.
PRODUCT LINE WISE, CISCO IS A WIDEST RANGE OF THE PRODUCT NOT ONLY IN THE FIELD OF R&S BUT ALSO IN COLLAB, WIRELES, DATACENTER, SERVICE PROVIDER, SECURITY, SDN , CLOUD , STORAGE & SERVERS ETC. FROM PIN TO PLANE, CISCO IS INTO EACH AND EVERY PRODUCT LINE OF THE NETWORK.AS COMPARE TO CISCO, JUNIPER IS MORE FOCUSSED ON R&S , SECURITY AND WIRELESS ONLY. BUT WE CAN SAY LIKE THIS.. WE ALSO NEED TO UNDERSTAND OR KNOW THE CISCO IS MORE THAN 2 DECADE OLD ORGANIZATION WHEREAS JUNIPER IS A JUST DECADE OLD…..
OPERATING SYSTEM WISE, IOS(CISCO-IOS) traditionally is a monolithic operating system, which means it runs as a single operation and all processes share the same memory space. Because of the latter feature, bugs in one operation can have an impact on or corrupt other processes. In addition, if a user wishes to add features or functions to the operating system, IOS has to be deactiviated while a completely new version with the desired features is loaded.JUNOS(JUNIPER OPERATING SYSTEM), on the other hand, was constructed as a modular operating system. The kernel is based on the open source FreeBSD operating system, and processes that run as modules on top of the kernel are segregated in exclusive, protected, memory space. Users thus can add features and functions to the version of JUNOS running on their systems without disabling the entire operating system — a characteristic known as in-service software upgrades that also enhances uptime and availability.
The goal of Cisco’s New-IOS Variant — IOS XR, IOS XE and NX-OS — is to overcome the monolithic limitations of the traditional IOS while addressing critical needs for increased uptime and availability in the service-provider core and edge, and enterprise data center, respectively. All these operating systems are modular, in that IOS services run as modules on top of a Linux-based kernel (in IOS XE and NX-OS), or as a third-party Portable-Operating-System-Interface (POSIX)-based real-time kernel (in IOS XR).
As for the processes themselves — establishing VPNs and security, assigning QoS, constructing MPLS label-switched paths, routing IP protocols, supporting multicast, and establishing IP addressing, among others — IOS and JUNOS are virtually identical. They both support industry standards specified for these tasks while going beyond the standards with proprietary techniques for their own equipment.
WE AT EIIT, IN OUR OR CCNA VERUS JNCIA PROGRAMS, INVITES GUEST FACULTIES WHO ARE FROM INDUSTRY WHICH EXPLAINS THE REAL-TIME SCENARIOS DEPLOYEMENT IN MORE PRACTICAL MANNER SO THAT CANDIDATE GOT TO KNOW HOW THEY NEED TO DEAL WITH SITUATION WHERE THEY ARE IN SUCH KIND OF ENVIRONMENT.
Simply put, cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics and more—Over the Internet (“the cloud”).
THIS IS BY FAR A BEST SOLUTION FOR OPEX OR PAY-PER-USE MODEL USE BUSINESS OPERATIONS.
Uses of cloud computing
If you use an online service to send email, edit documents, watch movies or TV, listen to music, play games or store pictures and other files, it is likely that cloud computing is making it all possible behind the scenes. Here are a few of the things you can do with the cloud:
- Create new apps and services
- Store, back up and recover data
- Host websites and blogs
- Stream audio and video
- Deliver software on demand
- Analyse data for patterns and make predictions
Top benefits of cloud computing
Cloud computing is a big shift from the traditional way businesses think about IT resources.
Types of cloud services: IaaS, PaaS, SaaS
With IAAS, you rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis.
Platform as a service (PaaS)
Platform-as-a-service (PaaS) refers to cloud computing services that supply an on-demand environment for developing, testing, delivering and managing software applications.
Software as a service (SaaS)
Software-as-a-service (SaaS) is a method for delivering software applications over the Internet, on demand and typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like software upgrades and security patching.
Types of cloud deployments: public, private, hybrid
v Public cloud
Public clouds are owned and operated by a third-party cloud service provider, which deliver their computing resources like servers and storage over the Internet. With a public cloud, all hardware, software and other supporting infrastructure is owned and managed by the cloud provider.
You access these services and manage your account using a web browser
v Private cloud
A private cloud refers to cloud computing resources used exclusively by a single business or organization. A private cloud can be physically located on the company’s on-site datacenter.
v Hybrid cloud
Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them. By allowing data and applications to move between private and public clouds, hybrid cloud gives businesses greater flexibility and more deployment options.
To Support the Growing demand of Internet Connectivity for Business requirement, Cost of WAN Services is going to have the significant impact on revenue (or Expense) of an organization. I-WAN is solution to provide the Solution to this Condition.
I-WAN stands for Intelligent-Wide Area Network. IWAN supplies you with all the business-grade capabilities of an MPLS VPN – such as quality of service (QoS), WAN optimization, and VPN tunneling – that you can put to work using less-expensive connections. As a result, you can grow your MPLS network using Internet, cellular, and other lower-cost links without compromising performance, reliability, or security.
IWAN dynamically routes your traffic prioritized by application, endpoint, and network conditions for best-quality experiences. The savings from IWAN quickly pay for any needed upgrades to your network infrastructure.
- Affordably extend your MPLS VPN with less-expensive Internet, cellular, or other WAN links.
- Reduce your monthly WAN services bill without reducing security, performance, or reliability.
- Use a single integration platform for all WAN control functions to simplify IT operations.
- Roll out guest Wi-Fi, SaaS, video, and other critical services without slowing down your WAN.
- Get a return on your investment in a matter of months
Virtualization is the process of creating a software-based (or virtual) representation of something rather than a physical one. Virtualization can apply to applications, servers, storage, and networks and is the single most effective way to reduce IT expenses while boosting efficiency and agility for all size businesses.
Benefits of Virtualization
Virtualization can increase IT agility, flexibility, and scalability while creating significant cost savings. Workloads get deployed faster, performance and availability increases and operations become automated, resulting in IT that’s simpler to manage and less costly to own and operate.
Additional benefits include:
- Reduce capital and operating costs.
- Minimize or eliminate downtime.
- Increase IT productivity, efficiency, agility and responsiveness.
- Provision applications and resources faster.
- Enable business continuity and disaster recovery.
- Simplify data center management.
- Build a true Software-Defined Data Center
Virtualization uses software to simulate the existence of hardware and create a virtual computer system. Doing this allows businesses to run more than one virtual system – and multiple operating systems and applications — on a single server. This can provide economies of scale and greater efficiency.
The Virtual Machine
A virtual computer system is known as a “virtual machine” (VM): a tightly isolated software container with an operating system and application inside. Each self-contained VM is completely independent. Putting multiple VMs on a single computer enables several operating systems and applications to run on just one physical server, or “host”.
A thin layer of software called a hypervisor decouples the virtual machines from the host and dynamically allocates computing resources to each virtual machine as needed.
Key Properties of Virtual Machines
VMs have the following characteristics, which offer several benefits.
- Run multiple operating systems on one physical machine
- Divide system resources between virtual machines
- Provide fault and security isolation at the hardware level
- Preserve performance with advanced resource controls
- Save the entire state of a virtual machine to files
- Move and copy virtual machines as easily as moving and copying files
- Provision or migrate any virtual machine to any physical server
Today is world of Fast and Reliable Communication wherein an individual can communicate and share useful information in a best, reliable and faster manner. Every industry demands “On the fly” decision so that Business is no longer dependent on the geographical boundaries. In order to achieve this Milestone in industry, Functional Requirement should no longer be Technology Dependent instead, Technology to develop, customize and implement based on the functional requirement.
In order to achieve this so called “ Anywhere Connectivity”,” “ Every-thing on the GO”, “ Single Sign-ON”, “Mobility” – MANY BUZZ WORDS ONE SINGLE DELOYMENT MODEL I.E. EVERY SUBSYSTEM IS NOW MIGRATING TOWARDS ONE SINGLE LANGUAGE TO COMMUNICATE, ONE SINGLE CODE TO UNDERSTAND ONE SINGLE WAY OF ADDRESSING THE VARIOUS SUSBSYSTEM AND THE SAME IS CALLED AS “MIGRATION TOWARDS IP”
THERE ARE MANY SUBSYTEM WHICH WAS EARLIER WORKING OR DEPLOYED ON SOME CUSTOMIZED APPROACH ARE NOW EVOLVED AS WORKING ON IP. THE NAMES OF FEW ARE: CCTV SYSTEM, SCADA SYSTEM, ACCESS CONTROLLER SYSTEM, PERIMETER SECURITY SYSTEM, BUILDING MANGEMENT SYSTEM, BACK-UP MANAGEMENT SYSTEM. THE MIGRATION TOWARDS IP PROVIDES FOLLOWING BENEFITS:
- FASTER DEPLOYMENT
- CENTRALIZED MANAGEMENT AND CONTROL
- BETTER BACK UP AND DISASTER RECOVERY MANAGEMENT.
- FEWER DEVICES ARE REQUIRED OF MORE OUTPUTS.
- NO MORE SINGLE OEM DEPENDENCY FOR USER.
- LESS MAN-HOURS / MANPOWER REQUIREMENT.
- MOST IMPORTANT MORE OUT PUT WITH LESS INPUT.
MOST IMPORTANT MORE OUT PUT WITH LESS INPUT.
WITH THE HELP OF THIS TEHNOLOGY INNOVATION, WE CAN ABLE TO EXECUTE VARIOUS MMP-EGOVERNANCE PROJECT WHICH ARE ACTUALLY LIFELINE OF THE MANY COUNTRIES.
AS THE IP COMMUNICATION IS NOW THE LIFELINE MANY PROJECTS, SO, MAN-POWER HAVING IP SKILL SET REQUIREMENT IS NOW INCREASING DAY-BY-DAY IN THE INDUSTRY. So, IT IS BETTER FOR ANY GRADUATE WHO WANTS TO PURSUE THEIR CAREER IN IT, SHOULD ATLEAST FOR MINIMUM BASIC OF NETWORKING TRAINING ATLEAST SO THAT THEY CAN RUN IN THIS IT REVOLUTION ERA…..
