microservices – Heterogeneous Data Integration for Enterprises – Combining Status Transfer with SOA

I work in a corporate environment that consists of several software packages – an ERP system, a CRM system, a transportation management system, an internet-enabled online ordering system, etc.

Some of these systems are developed internally, others are developed under contracts, and some (usually the "core" systems) are purchased off-the-shelf and some of them are customized.

It is to be expected that these systems are in most cases schematically heterogeneous and sometimes semantically heterogeneous (1), However, they all represent the same company in one way or another and therefore share common concepts – such as customers, orders, products, etc.

This question – or this discussion – is about how we could decide to integrate these systems. For example, if a customer's existence is determined by the ERP system, but the CRM system must be able to use customer information, how does the CRM system know what the status of customers is?

At the simplest level, in my opinion, it depends on deciding whether to copy the status to the polling time ("just in time") from a remote system to a local system, or to prematurely copy it, and I think that all patterns basically fall into one of these two camps.

For the remainder of this post I will refer to them as "JiT" (just in time) and "AoT" (premature).

An ETL-based approach – regardless of frequency, even down to "real-time ETL" or "event-carred state transfer"(2) – is clearly an example of AoT integration.

An SOA-based approach – including designs such as composite queries – is clearly an example of JiT integration.

Both approaches have strengths and weaknesses, and sometimes one or the other is required. For example, when I buy a CRM system off the rack, it is undoubtedly necessary to fill in your own internal customer data structure for it to work. Therefore, I must first copy the customer status from the ERP system to the CRM system. There is no possibility to leave the ERP-related customer attributes ONLY in the ERP system.

My basic battle at the moment is: what process should an architect choose, what should be integrated with AoT, and what should JiT be integrated? Is it realistic to claim, as the principle of enterprise architecture, that only one or the other can be used? I do not think so. But that means we use both, which means that there should be logical considerations that allow us to decide when to use one or the other.

After a few days of focusing specifically on this question, I have a hypothesis, and I would appreciate it if you would judge about it:

Hypothesis: The JiT integration should occur if and only if the disclosed functionality is a calculation

OK, what is a calculation?

A calculation is a business function that may require the use of state internally for an algorithm to be executed that is, however, in no way stateful to consumers.

An example of this could be a function like decimal GetPrice(string product, int qty), Internally, an information table may need to be looked up to perform the calculation. But any other system that calls this function is independent of this internal state and has no way to read from or write to it. This may be constructed as a microservice, or it may be one of a variety of functions provided by a monolith.

In contrast, the internal state of this machine may need to be filled out by other systems. It may need to be informed about products, customers, etc. The internal state of this system can (and therefore, by the statement of the hypothesis, must) are managed by AoT state transfer, which provides CRUD-like functionality as opposed to the computational functionality of JIT.

This is the claim you should judge if you wish. Does it make sense to differentiate between AoT and JiT based on whether a particular function is a "calculation" or not? Can someone see a logical problem with this taxonomy?

File Transfer – Is the Panasonic Data Port a standard USB Mini-B?

My Panasonic LUMIX DMC-GM5 has an unusual data port for transferring photos to the computer. The manual identifies the part as a USB connection cable DMW-USBC1. If I look it up, the official Panasonic page does not contain any additional information about the connection.

According to research, it resembles a USB mini-B connector. For example:

If it is the same connector (i.e., USB Mini-B) with the same pins, you can easily replace it or get a new USB-C connector.

My wife can transfer videos from her phone to our Chromecast, but I can not. What gives?

She has a Samsung Galaxy Note 8 while I own a Google Pixel 3. I can cast if the app in question (eg, YouTube or Hulu) supports Casting with a built-in cast button, but if I used the casting screen mirroring feature From the pull-down menu (for example, for an app that does not support casting internally, eg Spectrum) I can not cast videos – the part of the screen where the video is displayed will be black on the TV. That sounds like a kind of DRM problem, but why would it only affect my phone and not hers? Is there a way to transfer videos from my phone?

Where do I start to create an app like WiFi File Transfer?

I have a laptop and a tablet and I want to share files (mostly movies) through my home Wi-Fi network. I know there are apps / software for this kind of thing, but I want to create one for learning purposes from scratch. But I do not know where to start because I'm not familiar with network programming or networking in general (protocols, etc.). Can someone tell me where to start?

Interfaces – How do I program the P-L496G-CELL02 Discovery Kit to receive data over SPI and transfer it to the cloud over the NBIOT channel?

The P-L496G-CELL02 comes with the Discovery Board 32L496, the stmod + add-on and the Quectel BG96 module. https://www.st.com/de/evaluation-tools/p-l496g-cell02.html#tools-software

New in programming with this card is the hardware setup with a tag attached to receive data via the SPI2 pins. The connection to the CatNB1 network has been successfully established (using an included NBIOT SIM card).

The next step, receiving and sending the data over the NB-IoT network to the cloud (preferably Google Cloud Platform) and then displaying the received information, is a bit lost to me. Is there a way to code it to do this?

Any help would be very grateful, thanks.

video – FFmpeg does not seem to be able to transfer streams when remapping streams

I try to rearrange the streams of a video first in the form of video streams, audio streams, and then subtitles. I thought I could also change the format of the video mkv too frequent like mp4 but no matter what I try it still shows this error message:

Key Management – Is it possible to securely transfer a symmetric key to a VM instance using vTPM?

We have a Xeon physical host (Bare Metal BM Host) with a hardware TPM installed on it. The attestation status of the BM host is determined by start time measurements, which are captured and written to the PCRs on the TPM.

An agent program on the BM host sends a trust offer when a confirmation request is received. Each BM host uses a unique Attestation Identity Keypair (AIK) whose private key is bound to the TPM. The public AIK is shared with a KMIP key management system (KMS) which checks the host's acknowledgment status, wraps the key with the public AIK, and transmits the key to the BM host. The private AIK sealed in the TPM is unsealed and used to decrypt the KMS key.

The problem I am trying to solve is the secure retrieval of keys from the KMS. I was wondering if the same process could be applied to a VM instance using a virtual TPM (vTPM) or an emulated software TPM like the IBM implementation.

What are the challenges in this scenario and are there any alternative solutions I could try?

Bash script for the automatic transfer of panel accounts to directadmin

Hello everybody

I've created a bash script to automatically transfer cpanel user accounts to directadmin, which I'll share with you.
Hope it will be useful.

The script performs the following steps:

– Create a full account backup on cpanel. (This full backup does not include the public_html directory.)
– Transfer the backup to the DirectAdmin server and restore it.
– After the full backup in directadmin, the directory information of the public_html user in cpanel is transferred to the public_html directory in directadmin.
– Deletes full cpanel backups from both servers to avoid memory usage.
– Changes the account IP in the control bar to the IP of the DirectAdmin server to load the site from the DirectAdmin server.
– Stop the user in the cpanel server so that the user does not have access to the previous panel.

These steps are performed on each cpanel user account.

Note that you must add the DirectAdmin IP server from the "Add new IP address" section in the WHM area before running the script.
If you do not want to change the IP address after transferring the account, remove the following line from the script:
/ usr / local / cpanel / bin / setsiteip -u $ USER $ DEST

Note that the connection between servers must be made using the SSH key.

Important note that none of the cpanel accounts should be blocked! In this case, the script will not work properly.

You can see the script below:

Code:

#!/bin/sh
#You can get the script updates from  https://bit.ly/2ktJVHn

#Note that you need to add the DirectAdmin IP server from the "Add a New IP Address" section on the WHM panel before running the script.
#If you do not intend to change the IP after transferring the account, remove the following line from the script:
#/usr/local/cpanel/bin/setsiteip -u $USER $DEST

#Note that the connection between servers must be established via the ssh key.

#Important note that none of cpanel accounts should be suspended! If so, the script will not work correctly.
