OpenNebula Conf 2014 | State and future of OpenNebula - Ignacio LlorenteNETWAYS
We’re moving into a world of open cloud — where each organization can find the right cloud for its unique needs. A single cloud management platform can not be all things to all people, there will be a cloud space with several offerings focused on different environments and/or industries. The OpenNebula commitment to the open cloud flows directly out of its mission — to become the simplest cloud enabling platform — and its purpose — to bring simplicity to the private and hybrid enterprise cloud. OpenNebula exists to help companies build simple, cost-effective, reliable, open enterprise clouds on existing IT infrastructure. The OpenNebula Conference will be a great opportunity to remind our vision, vision and commitment, to look back at how the project has grown in the last six years, and to give a peek at what to expect from the project in the near future.
Current State of Affairs – Cloud Computing - Indicthreads Cloud Computing Con...IndicThreads
Session presented at the 2nd IndicThreads.com Conference on Cloud Computing held in Pune, India on 3-4 June 2011.
http://CloudComputing.IndicThreads.com
Abstract: Cloud Computing has had phenomenal growth over the past year and continues to entrench itself in all facets of IT. Cloud Computing is definitely more than just a buzz word or a passing trend. Now the heavy weights like IBM, HP and SAP are ready lock horns with existing players like Amazon, Salesforce and Microsoft whose offerings have matured over a period of time. Besides these big players, a lot of start ups are coming up with innovative offerings in this space.
The talk is about the current state of affairs in the cloud computing. It will cover the products, services and offerings that have been making a lot of noise in the cloud computing space.
Following are the main points that will be covered in the talk:
1. New Players: A lot of enterprise market giants are now coming to the cloud party offering infrastructure and platform services. IBM has come out with its SmartCloud for private as well as public clouds. Oracle has released its Cloud-in-a-box solution. The talk will cover all the new offerings by these enterprise giants.
2. Old Players, New offerings – Amazon being the leader in the Cloud Infrastructure space has rolled out a lot of new products and services, strengthening its hold in the market and expanding into the PaaS segment. Amazon Beanstalk, Amazon CloudFormation and EC2 Dedicated instances most notably have the power to be game changers. SalesForce the leader in the Cloud SaaS space released database.com, enterprise cloud database and its “PaaS” offering similar to GAE – VMforce.com This section will cover the new offerings by the players.
3 .Interesting Players in the cloud ecosystem: There have been a lot of new players who are leveraging the cloud to build some exciting products like Scalable API platforms, Cloud-based logging, Java in the Cloud. etc eg. Apigee, PiCloud, Loggly,Cumulogic, Cloudbees being some of them. This section will cover most of the exciting platforms and technologies these companies are working on.
4. Current Trends and Future: This section will cover the current trends(where a lot of startups are investing in) and how the future will look like in the cloud space.
Finally, the talk plans to “arm” developers and architects with the latest and cutting edge platforms, products and technologies in the cloud that have been developed and made available over the last year, helping them to leverage the cloud and make better choices leading to higher ROI and lesser TCO.

Introduction to Open stack - An Overview SpringPeople
OpenStack is a free & open-source software platform for cloud computing, mostly deployed as an IaaS. In this Slide, we will cover:
- Evolution of Openstack
- Cloud, its types and advantages
- Importance and overview of Openstack
- Openstack course syllabus
This was an intro I gave to create awareness with the Telco and enterprise community in Pakistan. The idea was to bootstrap this with an effort to create workshop content that will be created with collaboration from within Plumgrid (time /resource wise) and PTA as well as Govt. of Pakistan.
OSDC 2012 | OpenNebula Open Source Toolkit for DataCenter Virtualization by C...NETWAYS
OpenNebula is the open-source industry standard for data center virtualization. The presentation will describe its innovative features for the comprehensive, complete management of virtualized data centers to enable on-premise IaaS clouds in existing infrastructure. OpenNebula interoperability makes cloud an evolution by leveraging existing IT assets, protecting your investments, and avoiding vendor lock-in.
There is no doubt that Openstack represents one of the massive industry alignment towards the Open source cloud, Some even touting it to be the linux of cloud computing. But is it “THE” perfect solution ?
Vanilla Openstack is a “Myth”
The choice of Openstack as part of your cloud strategy purely depends on the kind of workload and the add-on features.
Openstack can be a serious contender especially for fresh deployments and applications that are being architected for cloud. But as the environment gets diverse(legacy integrations) Openstack can be tricky to integrate and maintain
One might require a vendor based Cloud management platform especially when the cloud strategy involves public clouds(AWS, Azure, GCE) and migration of application services across
No doubt it is fully open source, but it comes with learning curve, release cycles, Vendor specific driver integrations etc.
Interesting developments with respect to containers, docker, Kubernetes, Mesosphere etc will challenge Openstack
Openstack will no doubt will grow mature over next couple of years, until then, the hunt for the CMP continues...
Topics of interest :
to build a true hyper converged cloud ?
as an enterprise cloud management platform ?
public cloud ? (as a CSP)
Telco carrier grade cloud ?
VNF, MANO and SDN integrations

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

A Cloud Computing platform sits above the virtual data center and provides both a control plane over and resource access to the virtualized data center. OpenStack, as a Cloud Computing platform, manages virtualized resources, such as virtual machines exported by a hypervisor, network overlays created by Software-Defined Network devices, and volumes exported by virtual storage arrays. OpenStack takes these data center resources and automates and orchestrates them so they can be accessed on demand and be scaled up and down as needed, turning these resources into consumable services.
مفاهیم اولیه
سرویس ها و مدل های مشخصی وجود دارند که رایانش ابری را برای کاربران نهایی امکان پذیر و قابل دسترس می¬نمایند. مدل های رایانش ابری عبارتند از:• مدل های توسعه (Deployment Models)• مدل های سرویس (Service Models)
مدل های توسعه
مدل های توسعه نوع دسترسی به ابر را مشخص می¬کنند. به عبارت دیگر ابر برای استفاده چه کسانی طراحی شده است. ابر می¬تواند هر یک از چهار مدل دسترسی را داشته باشد:عمومی(Public)، خصوصی (Private)، ترکیبی (Hybrid) و انجمنی (Community)
ابر عمومی (Public)
ابر عمومی اجازه می دهد که سیستم ها و سرویس هایش به سادگی در دسترس عموم قرار بگیرد. به دلیل باز بودن ممکن است امنیت کمتری داشته باشد.
ابر اختصاصی (Private)
سیستم ها و سرویس های ابر اختصاصی تنها در دسترس یک سازمان بخصوص قرار دارد. به دلیل ماهیت خصوصی بودن، امنیت بیشتری دارند.
ابر ترکیبی (Hybrid)
ابر ترکیبی، آمیزشی از ابر اختصاصی و عمومی است که در آن فعالیت های حساس و محرمانه با استفاده از ابر اختصاصی و فعالیت های غیر حساس با استفاده از ابر عمومی انجام می گیرد.
ابر انجمنی (Community)
سیستم ها و سرویس های ابر انجمنی قابل دسترسی در مجموعه ای از سازمان ها هستند.
مدل های سرویس:
رایانش ابری بر اساس مدل های سرویس استوار است. مدل های سرویس به صورت پایه به سه دسته تقسیم می شوند:
زیرساخت به عنوان سرویس (IaaS) Infrastructure-as-a-Service
بستر به عنوان سرویس (PaaS) Platform-as-a-Service
نرم افزار به عنوان سرویس (SaaS) Software-as-a-Service
البته سرویس دیگری با عنوان هر چیز به عنوان سرویس یا (XaaS) Anything as a Service وجود دارد که شامل شبکه به عنوان سرویس (Network-as-a-service)، کسب و کار به عنوان سرویس (Business-as-a-service)، نهاد به عنوان سرویس (Identity-as-a-service)، پایگاه داده به عنوان سرویس (Database-as-a-service) و یا استراتژی به عنوان سرویس (Strategy-as-a-service) می شود.
زیرساخت به عنوان سرویس (IaaS) ساده ترین مدل سرویس است. هریک از مدل های سرویس مکانیزم مدیریت امنیت خود را از مدل های پایین تر خود به ارث می برد. همانطور که در شکل زیر نشان داده شده است.
زیرساخت به عنوان سرویس (IaaS)
IaaS دسترسی به منایع پایه نظیر کامپیوترهای فیزیکی، ماشین های مجازی، فضای ذخیره سازی مجازی و از این قبیل را فراهم می سازد.
بستر به عنوان سرویس (PaaS)
PaaS محیطی اجرایی برای برنامه های کاربردی و ابزارهای گسترش و توسعه فراهم می کند.
نرم افزار به عنوان سرویس (SaaS)
مدل SaaS امکان استفاده از نرم افزارهای کاربردی را به صورت یک سرویس برای کاربران نهایی فراهم می آورد.
تاریخچه رایانش ابری
مفهوم رایانش ابری در سال 1950 با پیاده سازی کامیپیوترهای Mainframe که دسترسی به آنها از طریق Thin/Static Client انجام میشد، مطرح گردید. از آن به بعد رایانش ابری از کلانیتهای ایستا به پویا و از نرم افزار به سرویس تکامل یافته است. دیاگرام زیر تکامل رایانش ابری را نشان میدهد.

In OpenStack a “tenant” is also called a “project.” I’ve always found the second name to be a clearer term and it appears that this is now the proper name going forward. From the OpenStack website glossary a tenant is “A group of users; used to isolate access to Compute resources. An alternative term for a project.” or a tenant/project is a set of any resources (compute, network, storage, etc.) assigned to an isolated group of users.

OpenStack, as a Cloud Computing platform, manages virtualized resources, such as virtual machines exported by a hypervisor, network overlays created by Software-Defined Network devices, and volumes exported by virtual storage arrays. OpenStack takes these data center resources and automates and orchestrates them so they can be accessed on demand and be scaled up and down as needed, turning these resources into consumable services.
The OpenStack platform is actually composed of multiple components, called projects. Each project is managed by a technical committee and the OpenStack Foundation decides which projects are ready to be included in the OpenStack core. These projects work together to provide the services required to deliver the Cloud.
Nova – The compute project responsible for on-demand creation and termination of compute instances. Nova leverage a number of hypervisors, including KVM, Xen, Hyper-V, and vSphere.
Glance – The OS image management project responsible for storage and management of images used to create compute instances with OSes installed, such as Windows and Linux.
Quantum – The network project that provides network access and security services to compute instances. Quantum uses plugins to leverage virtual switches and SDN-enabled devices.
Swift – The object storage project that provides a scalable repository for storing large quantities of objects such as files and media content. It can also be used as an repository for Glance images.
Cinder – The block storage project that provides a virtual storage array that can export out iSCSI volumes. A Cinder/virtual storage array server can be a server with local storage or a server using an external storage array.
Horizon – The interactive dashboard project that provides users and admins provisioning and management access to the OpenStack Cloud via a web GUI.
Keystone – The identity management project that provides authorization and access security control for all the other OpenStack projects.
New projects are being added with each release and as the OpenStack community calls for them. New projects underway include metering, application orchestration, and database-as-a-service.
