MegaTech Infoserve, Nashik presenting Biometric Time Attendance System

Bio-metric Attendance System And Access Control System

We deal in Bio-metric Attendance System and Access Control Systems. 
Bio-metric Attendance Systems are used by companies of all sizes to record working hours of employees primarily in order to pay their wages. Some companies have a requirement to record the number of hours spent on specific tasks in order to cost jobs accurately. Automated Workforce Management Systems can use electronic tags, barcode badges, magnetic stripe cards, bio-metrics (hand, fingerprint, or facial), and touch screens in place of paper cards which employees touch or swipe to identify themselves and record their working hours as they enter or leave the work area. The recorded information is then ideally automatically transferred to a computer for processing although some systems require an operator to physically transfer data from the clocking point to the computer using a portable memory device. The computer may then be employed to perform all the necessary calculations to generate employee timesheets which are used to calculate the employees' wages.

SaaS : Software as a Service

SaaS Software as a Service, is a new model of how software is delivered. SaaS refers to software that is accessed via a web browser and is paid on a subscription basis, monthly or yearly as per requirement. Different from the traditional model where a customer buys a license to software and assumes ownership for its maintenance and installation, SaaS presents significant advantages to the customer.

SaaS is faster and a cost effective way to getting implemented. There are no hardware, implementation or acquisition costs involved to run the application from the customer's side. It's the responsibility of the SaaS vendor to manage and run the application with utmost security, performance and reliability.

Since customers pay a subscription, they have immediate access to the new features and functionality. Unlike traditional softwares where upgrades would happen once a year or once in 6 months (with the vendor coming to your office with a CD), the SaaS vendor continuously pushes new updates, fixes to the application, which is immediately accessible by the customer. This reduces the length of time it takes a customer to recognize value from the software.

Since the software application is delivered as a service, its important for the vendor to focus on customer service and experience. Since this is on a subscription model, the vendor is judged on a month-month basis and the pressure to innovate or risk losing business is greater.

Adoption challenges

Some limitations slow down the acceptance of SaaS and prohibit it from being used in some cases:

• Since data is being stored on the vendor’s servers, data security becomes an issue.
• SaaS applications are hosted in the cloud, far away from the application users. This introduces latency into the environment; so, for example, the SaaS model is not suitable for applications that demand sub-second response times.
• Multi-tenant architectures, which drive cost efficiency for SaaS solution providers, does not allow true customization of applications for large clients, prohibiting such applications from being used in scenarios (applicable mostly to large enterprises) for which such customization is necessary.
• Some business applications require access to or integration with customer's current data. When such data is large in volume or sensitive (e.g., end users' personal information), integrating it with remotely hosted software is costly and/or risky.
• For applications or application suites that require access control and access-level permissions, you may want to delegate administration rights to clients. This reduces administration time and cost. However, this is difficult to implement and can expose your applications to additional security threats.

SaaS can be used by Windows, Linux, or Mac users, providing true platform independence over the Internet.

Cloud Computing

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities

·         Proven Web-services integration. By their very nature, cloud computing technology is much easier and quicker to integrate with your other enterprise applications (both traditional software and cloud computing infrastructure-based), whether third-party or homegrown.

·         World-class service delivery. Cloud computing infrastructures offer much greater scalability, complete disaster recovery, and impressive uptime numbers.

·         No hardware or software to install: a 100% cloud computing infrastructure. The beauty of cloud computing technology is its simplicity… and in the fact that it requires significantly fewer capital expenditures to get up and running.

·         Faster and lower-risk deployment. You can get up and running in a fraction of the time with a cloud computing infrastructure. No more waiting months or years and spending millions of dollars before anyone gets to log into your new solution. Your cloud computing technology applications are live in a matter of weeks or months, even with extensive customization or integration.

·         Support for deep customizations. Some IT professionals mistakenly think that cloud computing technology is difficult or impossible to customize extensively, and therefore is not a good choice for complex enterprises. The cloud computing infrastructure not only allows deep customization and application configuration, it preserves all those customizations even during upgrades. And even better, cloud computing technology is ideal for application development to support your organization’s evolving needs.

·         Empowered business users. Cloud computing technology allows on-the-fly, point-and-click customization and report generation for business users, so IT doesn’t spend half its time making minor changes and running reports.

·         Automatic upgrades that don’t impact IT resources. Cloud computing infrastructures put an end to a huge IT dilemma: If we upgrade to the latest-and-greatest version of the application, we’ll be forced to spend time and resources (that we don’t have) to rebuild our customizations and integrations. Cloud computing technology doesn’t force you to decide between upgrading and preserving all your hard work, because those customizations and integrations are automatically preserved during an upgrade.

·         Pre-built, pre-integrated apps for cloud computing technology. The Force.com AppExchange features hundreds of applications built for cloud computing infrastructure, pre-integrated with your Salesforce CRM application or your other application development work on Force.com.

Server Virtualisation

Server virtualization is the masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users. The server administrator uses a software application to divide one physical server into multiple isolated virtual environments. The virtual environments are sometimes called virtual private servers, but they are also known as guests, instances, containers or emulations.

Server virtualization is defined as the partitioning of a physical server into smaller virtual servers. In server virtualization the resources of the server itself are hidden (or masked) from users. Software is used to divide the physical server into multiple virtual environments, called virtual or private servers. One common usage of this technology is in Web servers. Virtual Web servers are a very popular way of providing low-cost web hosting services. Instead of requiring a separate computer for each server, dozens of virtual servers can co-reside on the same computer.

There are three popular approaches to server virtualization:

1.    Virtual machine model

2.     Paravirtual machine model

3.    Virtualization at the operating system (OS) layer.

Virtual machines are based on the host/guest paradigm. Each guest runs on a virtual imitation of the hardware layer. This approach allows the guest operating system to run without modifications. It also allows the administrator to create guests that use different operating systems. The guest has no knowledge of the host's operating system because it is not aware that it's not running on real hardware. It does, however, require real computing resources from the host -- so it uses a hypervisor to coordinate instructions to the CPU

The hypervisor is called a virtual machine monitor (VMM). It validates all the guest-issued CPU instructions and manages any executed code that requires addition privileges. VMware and Microsoft Virtual Server both use the virtual machine model.

The paravirtual machine (PVM) model is also based on the host/guest paradigm -- and it uses a virtual machine monitor too. In the paravirtual machine model, however, The VMM actually modifies the guest operating system's code. This modification is called porting. Porting supports the VMM so it can utilize privileged systems calls sparingly. Like virtual machines, paravirtual machines are capable of running multiple operating systems. Xen and UML both use the paravirtual machine model.

Virtualization at the OS level works a little differently. It isn't based on the host/guest paradigm. In the OS level model, the host runs a single OS kernel as its core and exports operating system functionality to each of the guests. Guests must use the same operating system as the host, although different distributions of the same system are allowed. This distributed architecture eliminates system calls between layers, which reduces CPU usage overhead. It also requires that each partition remain strictly isolated from its neighbors so that a failure or security breach in one partition isn't able to affect any of the other partitions. In this model, common binaries and libraries on the same physical machine can be shared, allowing an OS level virtual server to host thousands of guests at the same time.

Server virtualization can be viewed as part of an overall virtualization trend in enterprise IT that includes storage virtualization, network virtualization, and workload management. This trend is one component in the development of autonomic computing, in which the server environment will be able to manage itself based on perceived activity. Server virtualization can be used to eliminate server sprawl, to make more efficient use of server resources, to improve server availability, to assist in disaster recovery, testing and development, and to centralize server administration.
