  • Get your husband back from the other woman....... Get up and get your husband back from the claws of another woman. Don’t let those years you have invested in your marriage go to waste. Stop sulking and take action. I just got my husband back through the help of Dr Unity love spell Experts. My name is Emily Sarah am from Tx,USA. My husband left me for another woman, This was just 3 years of our marriage. The most painful thing is that I was pregnant with our second baby. I wanted him back. I did everything within my reach to bring him back but all was in vain, I wanted him back so badly because of the love I had for him, I begged him with everything, I made promises but he refused. I explained my problem to my friend and she suggested that I should rather contact a spell caster that could help me cast a spell to bring him back , I had no choice than to try it. I messaged the spell caster called dr unity, and he assured me there was no problem and that everything will be okay before 11 hours. He cast the spell and surprisingly 11 hours later my husband called me. I was so surprised, I answered the call and all he said was that he was so sorry for everything that had happened He wanted me to return to him. He also said he loved me so much. I was so happy and went to him that was how we started living together happily again.thanks to dr unity . if you are here and your Lover is turning you down, or your husband moved to another woman, do not cry anymore, contact Dr.Unity for help now..Here his contact, WhatsApp him: +2348055361568 Email him at: Unityspelltemple@gmail.com His website:https://unityspells.blogspot.com

  • I never believed in Spells or Magic until I met this great spell caster called DR ONIHA.. The man I wanted to marry left me 3 months after our wedding ceremony and my life was upside down. He was with me for 4 years and I really love him so much. He left me for another woman with no reasons. When I called him, he never picked up my calls and he didn't want to see me around him. I was helpless and didn't know what to do to get the man I love back in my life. I went online in search of help and I found the DR ONIHA website. I have to contact him. So when i told DR ONIHA what happened. he helped me to do some readings, and after the readings he made me to realize that the other woman has done some spells over my boyfriend and that is the reason why he left me.. he told me he will help me to cast a spell to bring him back. At first I was skeptical but I just gave it a try. In 4 days after which the spell was done by DR ONIHA, My boyfriend called me himself and came to me apologizing. I can't believe he can ever come back to me again but now i am happy he's back and we are married now and we live as a happy family. Am posting this to the forum if anyone needs the help of this great man, you can also contact him through this.  Email address: onihaspelltemple@gmail.com   Website: http://onihaspells.com Call/Whatsapp number: + 16692213962

  2. 2. 4 Built with Microservices & Functions ● Does one thing really well. ● Is stateless or relies on external state. ● Orchestrates across distributed microservices & functions. Event-Driven ● Sense and react to critical business moments. ● Event-first design pattern. ● Native support for event-first messaging & streaming (e.g. Kafka). Embraces AI/ML ● Services are becoming predictive and prescriptive. Deployable Anywhere ● Embracing Serverless/FaaS, Containers/PaaS and devices. Exposed via Open APIs ● CRUD/Resource based (REST). ● Query, Consumer APIs (GraphQL). ● Command based (gRPC). ● Asynchronous, Streaming (AsyncAPI). The Modern Application Change the Game with Cloud Native, “Anywhere”, Event Driven Microservices and APIs. © Copyright 2000-2020 TIBCO Software Inc.
  3. 3. 5 Extended With Evolving Patterns & Technologies © Copyright 2000-2020 TIBCO Software Inc. “By 2022, event-sourced, real-time situational awareness will be a required characteristic for 70% of new digital business solutions. And 80% of new business ecosystems will require support for event processing.” * * Source: Gartner; Top 10 Strategic Technology Trends for 2018: Event-Driven Model (Mar 2018) IoT / Edge Computing Serverless / FaaS Service Meshes Inclusion of Analytics (Batch + Streaming) APIs / AsyncAPIs Saga Design Patterns, Event Sourcing, CQRS ”Let It Crash” Scalable / Queryable Event Stores Event-Driven APIs for Decision Management ”Anywhere & Everywhere”
  4. 4. 6© Copyright 2000-2020 TIBCO Software Inc. The Modern Application: Powered By Events Traditional data processing simply takes too long! • Data is collected from a variety of sources, and placed in a persistent store. – Relational database. – NoSQL store. – Big Data environment. • Analytical processes are executed against the stored data to detect opportunities or threats. • Actions are identified, delivered, and executed across various business channels.Store Analyze Act
  5. 5. 7© Copyright 2000-2020 TIBCO Software Inc. The Modern Application: Powered By Events Traditional data processing simply takes too long! • Introduces too much “decision latency” into the business. • Responses are delivered “after-the-fact”. • Maximum value of the identified situation is lost. – Cross-sell / up-sell opportunities are lost, impending equipment failure is missed, business processes are slow to respond and lack timely context. • Decisions are made on old and stale data.Store Analyze Act
  6. 6. 8 ü In essence, events represent the way the world works. • Not only ordered streams, but true “event clouds”. ü Events represent a “change of state” in key business data elements. • IoT sensor reading, customer interaction, purchase transaction, patient admission, passenger check-in, … ü Events may be found in any vertical or business. • Government, healthcare, transportation & logistics, retail, finance, manufacturing, telecommunications, … © Copyright 2000-2020 TIBCO Software Inc. What Is An “Event”? Events provide value to the business.
  7. 7. 9 What Is An “Event”? Events provide value to the business. ü Events can come from any place, at any time, in any order. • Sometimes they don’t come at all, which is also important! ü Organizations must be able to handle events as a core component of their architecture. • Treat events with the same importance as data. • Microservices do NOT automatically mean “request-reply over HTTP”. ü Events are a mandatory component of today’s enterprise architecture. • Facilitate scaling & simplify fault tolerance. • Increase location independence & allow one to move towards loose coupling. • Reduce decision latency, handle events when they have the most value. • Eliminate expensive “polling for answers” which may never come. © Copyright 2000-2020 TIBCO Software Inc.

  14. 14. 16 The Modern Application: Event Contracts It all starts with the event contract. https://github.com/project-flogo/asyncapi https://www.asyncapi.com/ • AsyncAPI is to events as OpenAPI (Swagger) is to REST, or Schemas are to GraphQL. • Utilize AsyncAPI to build protocol- agnostic event contracts to: • facilitate code/documentation generation • support the creation of standardized event interfaces • improve event governance • TIBCO is a Platinum Sponsor of the AsyncAPI initiative. © Copyright 2000-2020 TIBCO Software Inc.
  15. 15. 17© Copyright 2000-2020 TIBCO Software Inc. The Modern Application: Event Patterns Some patterns to consider when building the modern application using events. • Event Sourcing • Persist the events that lead up to a particular state, not the state itself. • Easy to recreate a state at any point in time. • Other services (e.g. Big Data, streaming) can subscribe to event store changes. • CQRS • Command Query Responsibility Segregation • Services that handle updates are different from those that handle queries. • Utilize a “view store” to handle queries. • Events & Sagas • Use sagas to coordinate how a transaction is processed across many microservices. • Control sequence, compensate for errors, & trigger via events in a loosely coupled manner. • Can be centralized (“orchestrated”) or purely event driven (“choreographed”). • Commands (an action that starts processing, triggers an event) vs Events.
  16. 16. 18© Copyright 2000-2020 TIBCO Software Inc. The Modern Application: Event Patterns Using the guidelines of a Reactive Application. Responsive Resilient Message Driven Elastic Reactive Applications * http://www.reactivemanifesto.org/ • Coherent approach to systems architecture. • Reactive systems are flexible, loosely coupled, and scalable. • Use asynchronous message passing to establish a boundary between components. • To ensure responsiveness, the system must be elastic. • Failures must be met with elegance.

  19. 19. 21© Copyright 2000-2020 TIBCO Software Inc. The Modern Application: Event Patterns Using events (or the lack of events) in a contextual, declarative, temporal fashion. EntityState& Relationships In Memory, IMDG/DB, GraphDB, … Data Stream Contextual, Reactive State (Rules & AI/ML) • Event processing is not just about applying mathematical operations on time-ordered, unbounded data. • Business runs on rules and algorithms applied to context. • Logic is not always sequential, and may not be ordered. • Often more important to detect when things “do not” happen. • Manage “reactive state” in addition to events.
