Can somehow explain me the difference in these products?
As far as I understand IBM ACE (AppConnect) gives you more or iPaas capabalities. It is allows you to make an API.
But from what I understand now is that API Connect is required for the actual API management. Proxy/policies etc.
Does anyone know you these products are licensed? Do you have to API connect for your APIs to be managed, governed etc?
This is not an exhaustive answer, but hopefully it'll point you in the right direction...
App Connect is for building integrations (flows) with various data sources. Could be databases, cloud services like GSuite or Salesforce, or even HTTP endpoints. Those flows could be triggered by events in one of those systems or by an API. You can also do things like turn a database schema into an API. You get the idea.
API Connect is for API governance, security, and socialization. In more concrete terms, it gives you tools for things like: adding authentication and/or authorization to all APIs, bundling APIs together, enforcing rate limits or quotas, providing a portal for sharing/selling your APIs with others, and so on.
You can create APIs using App Connect and stop there--it's usable/invokable without API Connect in the picture. API Connect provides enforcement policies to give you more flexibility in how you call that API and/or give others the ability to invoke the API. The two products complement each other, but an API management product would be required in order to manage and govern the APIs created by App Connect.
In terms of licensing, there are multiple available options. You can purchase the products as standalone software packages that you install and maintain yourself (see IBM Cloud Pak for Integration) or you can leverage the IBM-managed versions that IBM provides via IBM Cloud.

I am getting confused on these 3 terms. What I know OCI is infrastructure provided by Oracle, IAM is user and IDCS is Identity cloud service. But I dont understand differences and terms.
Is IAM user and normal user are same?
is OCI and IDCS are same?
What exactly IDCS is?
Let me try to answer your questions:
IAM or Identity Access Management is a tool designed to control who access to your cloud services. IAM user is an user who access to a service in your Cloud. What do you mean by normal user I cannot know.
OCI or Oracle Cloud Infrastructure, is a deep and broad platform of cloud services that enable you to build and run a wide range of applications in a scalable, secure, highly available, fault-tolerant and high-performance environment.
Oracle Identity Cloud Service (IDCS) is an Identity-as-a-Service (IDaaS) solution available in Oracle Cloud. It is designed to extend enterprise controls by automating PaaS and SaaS account provisioning and deprovisioning, simplifying the user experience for accessing cloud applications by providing seamless integration with enterprise identity stores and authentication services, and facilitating compliance activities by clearly reporting on cloud application usage.
Although it look like IDCS and IAM might look the same, they are designed to different purposes. IDCS is focused on SaaS or PaaS services by integrating itself with identity stores as Active Directory or LDAP inside organizations. IAM is designed to control Cloud resources providing access to each component, like a block storage or a computer instance.
Hope it clarifies a bit.

First of all
OCI refer to Oracle Cloud infrastructure and it's cloud computing solutions same as MS azure or amazon AWS, but offered by Oracle and it's providing various services such as servers, storage, network, applications and services through a global network of Oracle Corporation managed by different data center around the world.
IAM refer to Identity and Access Management this is services allow you to control who can access to cloud resource and even control what type of access they have, and to which specific resource, there is different Components of IAM such as resource, user, group and more you can check Oracle documentation that provide also examples here
IDCS refer to Oracle Identity Cloud Service and it's consider as Identity-as-a-Service (IDaaS) solution, Oracle Identity Cloud Service provides identity management, single-sign-on (SSO) and identity governance for applications on-premise, in the cloud and mobile applications , Any user can access the application at any time, anywhere on a device in a secure manner. Oracle IDCS integrates directly with existing directories and identity management system, making it easier for users to access applications. Providing a platform that is robust and secure, allows users to access, develop and deploy their applications.
Check the documentation here
The benefits of implementing Oracle Identity Cloud Service are; Improved Business Responsiveness, Enhanced User Productivity and Experience, Hybrid Multi-Channel Access and finally Simplified IT and Reduced Cost.
In addition to the answers above, IDCS can play role of IDP for federated login to Oracle Cloud Infrastructure console.
I'm choosing a serverless platform for my projects. I have explored AWS and found it excessively complicated: they provide an enormous bunch of settings but some basic scenarios are been too hard to implement.
The other platform looking promising for me is IBM Cloud with its OpenWhisk. And I'd like to check if the necessary capabilities are either implemented or in close plans for implementation.
Questions
Can I use websocket for my functions as a trigger for connect, message and disconnect? I found only a half year old discussion and nothing more. But this feature is demanded for real time applications.
Can I have static websites in both my custom domain and in subpath? I saw recipes where a docker container and lambda functions were employed. But writing my own implementation of Nginx looks nonsense. But this feature is also strongly demanded for single page applications (SPA) and there can be multiple such SPAs on one domain.
This blog with an IBM Cloud Functions overview has links and answers to your second question. There are tutorials on how to use custom domains with IBM Cloud Functions as backend for applications (see this tutorial with static page / SPA custom domain, and recipes for Express and Flask).
IBM Cloud Functions also has a package to post to Websockets. AFAIK there is functionality to listen to Websockets. My understanding is that serverless is incompatible with the "always on" nature of Websockets and the serverless runtime would need an API gateway or similar to manage the communication. If something is received, the action would be invoked.
Support for websockets for the ActionLoop proxy (used by Go,Swift,Python,PHP,Rust and Java) is here: https://github.com/sciabarracom/incubator-openwhisk-runtime-go/tree/websocket-support.
It can be used to build runtimes that support websocket but you need to deploy the runtime by yourself using Kubernetes. The support had ben postponed as an integration of OpenWhisk with Knative is a better path to include it in OpenWhisk.
I am currently working heavily in Azure. I am actually quite fond of ARM (Azure Resource Manager) right now and would love to keep using it. Right now in the old portal, We have a lot of resources tied up as Cloud Services. Now, I know cloud services are available in the new portal, but it seems that Microsoft is moving away from the classic cloud service model. Can someone explain if this is true? If so, what will the new model look like? I already use resources groups to manage Websites (WebApps), so I assume this is where the azure future lies. Will we see the "deprecation" of cloud services on down the line?
I am trying to understand if I need to begin re-structuring my Azure Infrastructure.
Any insight, explanation, or documentation is greatly appreciated.
So there are two things here - Cloud Services and managemenet of Cloud Services.
When you manage Cloud Services in current portal the underlying mechanism used is Azure Service Management (ASM) where as it is Azure Resource Manager (ARM) in the preview portal. To me, ARM is the new way of managing your Cloud resources in Azure (including Cloud Services).
I don't work for Microsoft so I would not know if Cloud Services themselves will be deprecated down the road or not but one thing I think will happen is that ASM will be deprecated in favor of ARM. At some point of time, the only option you will be left with managing your cloud resources will be through Azure Resource Manager. One example that makes me believe this thing is the presence of Classic resource providers (e.g. Classic Storage Resource Provider which enables you to manage storage accounts created in current portal via ASM in the preview portal which works exclusively on ARM).
Personally I can't see a place for cloud services in the new ARM world of Azure. I have always found them a convoluted concept that simply added complexity to a deployment.
In the ARM view of deployments servers are collected together in a VNet, and each server is attached to a Nic which in turn can be connected to the internet. A security group then takes care of ingress / egress rules.
This is a much cleaner deployment method, as it puts connectivity configuration at the server layer instead of mapping them all through a higher layer of abstraction.
I don't see the place of cloud services in ARM, however after a quick search it seems that there is a plan to implement it
Still no direction from the Azure Advisers group other than officially they will not drop support for Cloud Services. I think they are nearing giving us some kind of direction but I can't say anymore than that.
I asked a question about the future of Cloud Services on the recent Azure Compute AMA.
You can read the answers directly on Reddit for all details, below are a few interesting quotes (emphasis mine).
On ARM Integration for Cloud Services:
We are looking at ways to make the transition to ARM easier for Cloud Service customers- one of those options includes CS integration in ARM. This investigation is in the very early stages though, so if you are looking for a solution soon, check out VMSS/ACS/SF/Web Apps (meagan-msft)
And:
I think it's safe to say that if we make any significant investment in CS in the near future, it would be ARM integration, and as Meagan suggests, that's still in planning. Beyond that, there are no major feature improvements on the horizon. We believe the platform is pretty mature at this point. (seanmichaelmckenna)
So it doesn't look like any major innovations will hit Cloud Services soon, however:
Cloud Services are not going anywhere. In fact, many Microsoft services run on Cloud Services, so we heavily rely on them as well. They are fully supported, so feel free to continue to use them.
(meagan-msft)
For those who want to switch to a different Compute service, these recommendations were made:
However, if you would like to check out other services that are integrated with ARM today, we recommend checking out the following:
Web Apps for customers who want a fully managed platform and are building traditional web applications
Service Fabric for customers who want an opinionated application platform and managed infrastructure, but still need some control over the IAAS layer
VM Scale Sets for customers who need IaaS-level control with easy scaling, autoscale and load balancer integration
Azure Container service was also listed as a potential alternative.
Some things to consider (my understanding):
Service Fabric currently (2017) requires at least 5 VM instances, except for dev/test purposes. So probably only an option for larger services
VM Scale Sets is an IaaS offering, i.e. you have to manage OS updates etc. yourself. However, support for automatic OS updates is being worked on.
I am creating a system where a CEP engine looks like a good fit (I need detect time based patterns between events in a number of streams). The events detected need to be displayed to end users in a WPF application but not all users are entitled to see all events.
How is this typically handled when using a CEP engine? Do I need an additional service layer between the UI application and the CEP engine or can it be done in the CEP engine itself?
I'm not sure there's a "usual" answer to this question across all CEP engines. CEP engines are really not at all uniform in the services they provide.
You tagged this question with "streambase", so I can talk about that some. The StreamBase CEP runtime has support for user authentication when creating a client connection to a server to dequeue tuples from output streams. People typically hook this up to their local LDAP or AD server.
That said, there's no per-tuple dequeue authorization/entitlements enforcement mechanism in the StreamBase CEP runtime, at least as of the current release (7.3).
So, when StreamBase users want per-tuple entitlements enforcement, we usuallygude them toward building that in at the application layer, or use some other piece of available infrastructure. For example, rather than using native StreamBase Client connections, use an adapter to something like TIBCO EMS or IBM MQSeries and use the per topic/queue entitlements there to restrict access. Or as another example, have the StreamBase server send back a token to an authenticated user after connection, and use that token as a key for entitlements checks on the client side against LDAP using a dequeue interceptor.
Or, as you say, use your own services layer.
There's another example of "Poor Man's Entitlement Service" on the StreamBase Component Exchange. Search for "StreamBase Entitlements". This uses an in-memory or JDBC database to store users, roles, and entitlements and applies them on the server side with an efficient runtime entitlements checking mechanism. But there's no strict runtime restriction on the connections with this; it's just an example of implementing entitlements functionality with a nice UI. The clients voluntarily respect the restrictions, which is probably not what you were asking for.

I have to integrate my web service with IBM Enterprise Service Bus (ESB).
I think that there should not be any mediation because this service has only one location
and do not have to change requests.
Is it true? Can ESB administrator simply connect web service to the bus?
If it is necessary to write mediation code:
are there any free tutorials and tools to create such mediation
or I have to buy WebSphere Integration Developer (WID)?
This mediation should be simple and I don't want to spend money on something
used once.
Disclaimer: I'm a WebSphere ESB consultant for IBM.
The answer to your question depends on what you're expecting WebSphere ESB (WESB) to do for you. If you're simply trying to connect a Web Service consumer to a Web Service provider, you don't need need WESB to do that. However, typically folks want to use WESB because they either want to put some logic between the two (maybe transforming from one Web Service interface to another, for example), or because they might want to later. In either case, you'll need to create a mediation module to do that - there is no bus per se that you just connect services to.
In practice, you will need WebSphere Integration Developer (WID) to do that - it would be a lot of work to create the mediations manually, it's not documented, and it's not supported by IBM either. Your local IBM client team should be able to advise you, but these products are typically purchased together.
Hope that helps.
There are several ESB's in IBM's portfolio. The only one that don't really need WID is IBM WebSphere DataPower (I don't know enough about Lombardi to comment). If you have choice, I would use that to get your company started down this path.
