SAP on SUSE Linux Enterprise Server with XEN Virtualisation

May 26, 2020 No comments

We have SAP running on SUSE on XEN virtualization for 8 years without any glitch. We have to keep in mind the this was the early stages of virtualization we had to take great care as SAP was expensive tool and if the base virtualization fails, then my and organizations reputation was at stake.

To make things complicated the existing Microsoft Dynamic ERP was to be migrated to new SAP.

The race was between VMware, KVM and XEN

How SUSE XEN won the race. First SAP was supporting SUSE platform and SUSE was supporting XEN, so the entire platform was being supported

KVM lost because at the point of time we did not get any support next competitor was VMware, the client was very particular on costing and ease of expansion in the latter.

VMware proposal was, it provided limited VMs and over every VM there would be license cost and again a lock on a number of core and memory usage, this was a bottleneck if the organization was to expand, it will have to yield to VMware's demand, So the client asked for alternative and best alternative was XEN no limitation on VMs and Memory usage, and CPU core was also not a limitation.

We did not stop at these findings, we wanted to test XEN failover and VMware failover, both did a prototype for testing.

VMware cluster failover and Vmotion was seen with system not available to users during the fail-over around 5 minutes. Which was a bit concerning to all of us. Otherwise the failover happened and the other system came up successfully.

SUSE XEN was also put to test on the same test hardware, the flavor was almost pretty smooth we did not notice and noticeable non-availability to users. Only issues was we had do all in command line.

Both were demonstrated to client, client decided on XEN based on cost, support and performance test results.

One highlight of VMware had pretty user friendly Admin GUI interface, which SUSE XEN lacked, but the client was in the view that command line interface is better as people who are not experts will not touch the servers.

At that point of time VMware also was new to bare-metal implementation, were XEN score well over VMware. But today XEN is nowhere to be seen, VMware is seen as the king of virtualization and KVM also has better market after many companies have started supporting it development.

The SAP Architecture we used was Three Tire model, we have two physical servers and 4 VMs, for Production, Application, Database and Sandbox

I had a team of Basis and Abap developers and everyone worked in sync for this project. One of the major problems was backing up the VM, so to take snapshots , we had to allocate huge space in storage for the same, regular backup from DB2 database, DB2 was used as the client wanted to reduce costs further.

SAP HANA 9 Pros and Cons

May 25, 2020 Consulting, Resume, SAP, Server No comments

Advantages over SAP HANA

Let me start with benefits of, SAP HANA:

1. SAP HANA presents real-time evaluation then decision-making capability. It enables technology over extensive amounts of information while the commercial enterprise is running on. Thus, that gives immediate real-time insights.

2. The in-memory database technology makes records processing yet transactions very quick by smart thinking process from RAM. Therefore, facts perform lie immediately and rapidly processed beyond any know database.

3. SAP HANA lets in information stored and processed in columns and rows of the database. Also, many operations parallelly processed in SAP HANA namely opposed traditional RDBMS technology in the typical database for processsing some query. Thus, analogy is parallel processing technology will increase the speed of function multifold.

4. In traditional database, customers do use solely one on the transactional strategies (OLTP then OLAP) at a time. But, in SAP HANA’s in-memory database, customer is able to get retrieve data from more than a few databases for each transactional (OLTP) than analytical (OLAP) queries parallelly all at once.

5. You can acquire information besides various external facts sources that fit the source-agnostic capabilities concerning SAP HANA. Also, that makes the SAP HANA to function similar with distinct DBMS aged across the organization. Thus, enabling handy information integration. Without interrupting the continuous commercial enterprise operations, you execute perform records integration or total out of various capabilities or records sources within SAP HANA. You do additionally combine that with SAP Business Object BI solutions by using tools like SAP Lumira, Web Intelligence, SAP Crystal Reports, Design Studio, Dashboard designer, Universe Designer (IDT/UDT), BusinessObjects Explorer, Analysis Office, MS Excel.

6. If the power fails for some reason the Persistent Data Repository will ensure that your business is recovered in case of a breakdown. By the real-time facts counterpart service, we can perform replicate the information between old SAP ERP and SAP HANA , not distributing existing operations of the enterprise suite.

7. For third-party software access, it may use features regarding SQL/MDX.

8. Using data modelling and devising tools, data models are performed virtual. It also makes the procedure over modeling and re-modeling altogether easy.

9. Admin Cockpit correctly manages and display various parameters of units of SAP HANA making life easy.

Disadvantages partial limitations of SAP HANA:

1. SAP HANA generally runs on SUSE Linux licensed hardware. It creates a problem because if the customer wants to run on any other hardware, the expenses concerning licensing are altogether high.

2. Limited hardware utility according to use SAP HANA a pricey investment.

3. SAP HANA does no longer supports all ERP products because of their different types of architecture. SAP HANA requires ERP users to change their architecture in imitation of redacting such HANA compatible.

4. The older version becomes out of date at all soon, this due to the face SPS releases and updates in the SAP HANA versions. And, it would be concerning by person handing ERP, each time and updating is time-consuming.

5. It has been noticed that SAP HANA server shut down at times of heavy data processing and calculation load.

6. Using hybrid solutions regarding HANA like walking that incompletely concerning the cloud integration , incompletely on-premise reasons a cluster about problems and doesn’t feature properly.

7. Usually, builders whosoever nonetheless proceed along their historic ways about assignment along with database technologies, are not capable of conformity with using SAP HANA to its complete potential. They solely utilize that as a quickly in-memory database, while even are deep other capabilities yet functionalities that SAP HANA provides.

8. SAP HANA appliance only certified in IA platform.

9. The relative new HANA Database is still addressing issues of that are related new products.

What to expect in the future of AI?

May 24, 2020 Artificial Intelligence, Consulting, IOT, SAP, Travel No comments

I made an attempt to write about AI here: https://gkarvind.blogspot.com/2020/05/how-does-artificial-intelligence-work.html informing you about how AI works, now this article is about what to expect in the future of AI?

Machines will become our most reliable friends, advisors, and caretakers, We will be living in symbiosis with AI, We will reach immortality by keeping out mind alive in the cloud, Humans may not have to work anymore, We will have to rethink the value and purpose of the human mind and body.

FACTORIES

With Industry 4.0 in, the factories are seeing incresing usage of IoT and AI, The most of the process will be handled by AI, leading industry ERP application makes like Oracle, SAP etc. Have rolled out AI functionality, it can manage right from raw material procurement to delivery of the products to clients all on its own, you just need some rules set as per your business needs, paving way for future ultra efficient manufacturing units.

Veo Robotics combines 3D sensing, computer vision and AI to make robots safer to work with in a manufacturing setting without the need for cages or operations shut-downs to perform inspections. Mythic another company wants to create IPU's powerful enough to let robots and drones communicate conversationally so they can respond and react to situations in real-time.

MEDICAL DIAGNOSIS

The simple fact is that the human has produced a more overall understanding of human health than any one human brain can usefully contain, and A.I. As it has only one function will quickly start to out-perform even the best of best human doctors. In 10 years time, how many people will be willing to opt for AI Doctors is something we will have to get used to.

PATHAI is using AI for accurate cancer diagnosis, Harvard University’s teaching hospital, Beth Israel Deaconess Medical Center, is using artificial intelligence to diagnose potentially deadly blood diseases at a very early stage

COOKING

Cooking is perfectly suited to A.I., since it basically just requires knowledge of how a list of ingredients get combined in different ways, in different amounts. AI will check the market price of products and your health conditions, and provide you with the best cost effective meal. AI will check your fridge and stores and tell you what can you cook with the ingredients present. AI will also order your groceries and vegetables and pay from your bank account all by itself.

AI-enabled Chef Watson is a project by IBM and functions as a digital culinary research assistant (sort of like a genie/oracle) with access to a database rich in flavor profiles and recipe ratios — rendering the Flavor Bible obsolete.

LEGAL ADVICE

For high-level lawyers, it’s precisely the ability to see around the rules that make a successful lawyer. Where AI, could really change society, at a deep and fundamental level, it will provide defense to those who cannot afford a competent human for representation. AI can read thru millions of legal documents and find ways to help you come of the case unharmed.

Alexsei is a service for answering complex legal questions at scale. By design, we are aggregating the world’s legal research data in order to build a truly autonomous lawyer. Specifically, Alexsei is a web-based platform that provides a fast and affordable service for lawyers to get answers to their legal research questions and a user interface for lawyers to manage all their legal research data. fewmore in the race are CiteRight Inc., legali.city, optimizelegal.com

FARMING

The AI takes over farming practices, it will read the sensors that will tell how much nutrients and moisture is needed for a particular plantation, it can talk to the AI, weather system and decided what would be the best time to spray fertilizer, water them, cultivate them. Even the cultivation will be done my machine that is AI driven, harvesting, cleaning, sorting and packing for the market.

Bengaluru-based Intello Labs was started by IIT-Bombay alumnus Milan Sharma in May 2016. The company claims to provides advanced image recognition technology that can recognize objects, faces, flora fauna and tag them in any image.

FINANCIAL SERVICES

Bank automation is making some bank employees move to unemployment, When the A.I. Really take over. The financial services sector as of now has a lot to do with rich get richer they can afford to hire more and better financial help to manage the money they have. With A.I., especially open source fintech solutions, it could be possible to change personal finance to put it on a much more even playing field. As the AI cashless transaction model improves ATMs will disappear along with it the cash loading jobs.

AI assistants, such as chatbots, use artificial intelligence to generate personalized financial advice and natural language processing to provide instant, self-help customer service. Take any bank ICICI, SBI they have started using this technology.

TRANSLATION AND LINGUISTICS

I am not going to talk much about as you see that you can talk to devices and they respond, some devices help to you talk in another language that you don't know.

DEFENCE - CYBER and TRADITIONAL

No matter how talented the security expert, they simply cannot hold a wall to the speedy attacks of an automated botnet. We will see large proportions of cyber-security offloaded to automated techniques.

The country borders will be safe with AI, they will take care of various inputs and generate alerts and even firearms if needed. Give instruction to drones that will carry out attack without any human intervention, with less collateral damage.

A main focus of Sophos‘ cyber security services is on endpoint protection using Ai, which is carried out through its Intercept X Endpoint product, Fortinet company also offers Ai-powered firewall technology in the form of FortiWeb, which features threat detection for web applications guided by two layers of statistics.

TRAFFIC

The traffic will be in the future in completeness will be maintained by AI, the upcoming AI autonomous vehicles will talk to the traffic AI and both together will decide how to reach the destination in the most economical way. You will mostly read a book of your choice on the way and spend less time on the road.

When you want to go on a road trip AI will make all the decision of fuel consumption, best time to drive, book tickets are restaurants on the way, etc.

Siemens has AI-based Traffic and City Mobility Solutions develop data- and AI-driven applications and services for even smarter management of road traffic, fleets and intermodal mobility.

POLITICAL ANALYSIS

Donald Trump has used this technology and others are following, some companies are making robots to read news that can articulate with a vast amount of news that available on the fly. Will see the end of newsreaders in future.

Cambridge Analytica was one such company there are others in the game too.

BETTING

Fetiche number are being used to predict stock market the same also for betting, now with AI it will churn out all the data from history and provide you with the most appropriate betting direction.

https://www.helios.ai/ has worked on horse racing betting model

RUNNING A BUSINESS

Human intelligence and ingenuity, artificial intelligence is generally seen as a supporting tool in business. AI will be driving your business, right now we have a supermarket that is unmanned, you just walk in take the product you want the network of sensors and cameras identify what you have collected, and by the time you reach the checkout the AI would have kept all the numbers ready and for your approval the payment will be transferred from your account. It will also suggest what you have bought by telling you what you are running short at your home.

AI can be seen in CRM, handing customer effectively, SAP has developed a cloud platform specifically for AI related works, such as image processing, AI analytics for predicting.

PERSONAL ASSISTANT

Many of us will have an AI personal assistant, which will help in organizing out day to day chores. It will take notes on meeting, it will remind, fix a salon appointment, inform your client if you are late.

It not difficult to see examples here, apple Siir, Google Alexa, Netflix,Nest are excelent users of AI.

AI is better or does it have some sedate side-effects? But I do know that we can’t stop the evolution, and we have to think hard and work smart to keep up. Adapt our linear thinking with the exponential growth of technology.
