Can you please tell me how is Cloud DB different from Huawei Cloud?
Can I have the same parent-child relationship while storing data as, i get on firebase in Huawei Cloud?
Also since Cloud DB is in beta, does that mean i cannot release the app on AppGallery Connect?
Cloud DB is a scalable serverless database product provided by AppGallery Connect (AGC), it supports device-cloud data synergy management, provides a simple and easy-to-use native SDK for multiple platforms - Android apps, iOS apps, and web applications can directly access Cloud DB through the SDK. Cloud DB uses the data storage structure based on the object model. Data is stored in different Cloud DB zone as objects. Each object is a complete data record. An object type is used to define a set of stored objects. Different object types correspond to different data structures. A Cloud DB zone is an independent data storage area. Each Cloud DB zone has the same object type definition. You can define object types, create Cloud DB zones, and manage data on the AppGallery Connect console. Cloud DB supports multiple Data Types, including simple character strings, digits, and texts.
When you say "Huawei Cloud", it is a broad term, this term mainly refers to the enterprise Huawei Cloud similar to Alibaba Cloud, AWS, Azure, etc. There are many database services in Huawei Cloud such as RDS, GaussDB, DDS, DRS, DAS, etc. These databases are designed for enterprise use cases like IoT, e-commerce, finance, web, mobile gaming, e-government.
AGC Cloud DB is an alternative to replace Firebase Realtime Database however it simply stores an object and does not provide parent-child relationships. If you are looking for object type, parent-child relationship storage in Huawei Cloud, you can consider GaussDB for Mongo, GaussDB for Cassandra. Please consider how you would like to access data in your product before choosing the best database.
Although AGC Cloud DB is in beta, you can use it in your app (free tier quota only) and release it in AppGallery. Please check out the supported platforms here and quota/charges here.
When you apply for the Cloud DB service for the first time, if your application requires more resources than the free quota, or if you have enabled the free Cloud DB service but the free resource quota cannot meet your application requirements, you can download and fill in an application form, and send it as an attachment to agconnect#huawei.com.
Cloud database Service of HUAWEI Cloud is used for web development and web application setup.
AGC's Cloud DB is a cloud database service for mobile application development.
https://developer.huawei.com/consumer/en/doc/development/AppGallery-connect-Guides/agc-clouddb-introduction
The beta state only restricts developer's access. Developer who have applied for the use can use the application as will, and they can release their applications, released applications are not affected.

I would like to know what is exactly firebase. When i want to create authentication for my app i see on google firebase is often used on flutter for do it but it is not clear what is it exactly. I have a MySQL/php api from the server side and i need to find a way for save on mobile phone an user id when the user create an account, what is the best solution for do that with security. I have seen too, there is people who uses shared preference but security is low i think
Firebase is a whole set of applications and services that acts as a link to Google Cloud, which provides these services. Here's their website.
Firebase is a toolset that (according to them) allows you to “build, improve, and grow your app”, and they give you the tools that cover a large portion of the services that developers would normally have to build themselves. This includes things like analytics, authentication, databases, configuration, file storage, push messaging, etc.
This is different than traditional app development, which typically involves writing both frontend and backend software. The frontend code just invokes API endpoints exposed by the backend, and the backend code actually does the work. With firebase, your app accesses those services directly (or, allows you to write APIs to handle that, if needed)
These are the firebase functions that (arguably) are the most commonly used amongst developers.
Authentication — SECURE user login and identity, with applicable
rules
Realtime Database — realtime, cloud hosted, NoSQL database (older
version)
Cloud Firestore — realtime, cloud hosted, NoSQL database (but with
better queries)
Cloud Storage — massively scalable file storage
Cloud Functions — “serverless”, event driven backend (this is where
you'd write your
APIs)
Firebase Hosting — global web hosting (this is GREAT for flutter
because you can upload your designs immediately without paying for
it.)
ML Kit — SDK for common ML tasks
Here are all their services... but I haven't used most of them.
Finally, the great thing about firebase is that all their functionality is free, and you only start paying when the traffic starts growing.
Is it the best choice for authentication? Without. a. doubt. Not only is it secure, it provides a wide range of side services like "login with your google/facebook/whatever account" and "Forgot your password" retrievals. But it also allows for full token authentication, and access rules.

as u have api already then what u can definitely use firebase for verifying the phone number of user & then continue him to register that way u can get verified phone number of user.
u dont have to save phone number of user u can get it using
await FirebaseAuth.instance.currentUser().phoneNumber
what shared preference is used for is to store basic info about user like phone number, username, isLogin etc. but if u care about security which i dont think u need to worry about u can use another package like hive which uses AES 256 CBC with PKCS7 padding encryption.
This question already has an answer here:
Why is it okay to allow writes into Firebase from the client side?

If I use the prod environment variables in my App and set the server side rules for Firestore, would my app be completely secure to perform CRUD and authentication? I am asking this because I have been seeing Angular tutorials by pretty famous YouTube content creators (Fireship) and they do not touch server side code and still show how to make a production applications. All the tutorials use only Angular and some libraries to produce the apps and features but then the console on Google says not to expose the API keys. Using only client side Angular even in production environment variables exposes the private keys right?
So in short, should I be using Node to CRUD and Auth with Firestore, or server-side rules on the console works safe?
The configuration that you use on the client to get it to communicate directly with Firebase services is does not include a private API key. Much has been said about this in various forums over the past few years. The thing you see that might be labeled an API key is actually public information. It helps the client library locate the project it's working against. The API keys you want to hide are those that exposed direct access to other billed services, including Google Cloud service accounts.
You limit access to Firebase backend services (Cloud Firestore, Realtime Database, Cloud Storage) using security rules to determine what a user can or can not do with the data stored in it. If you don't do this correctly, you could have problems.
Whether or not you want to let the client access the services directly or make the client go through some middleware you write should be decided by other reasons, as discussed in this article.
I was hosting my node app on Heroku connected to a mongolab for the DB.
Thanks to a few tips from here, I've deployed my app code to Bluemix. I moved mainly because I'm changing databases from mongodb to couchdb, and am hoping that Bluemix might have a faster connection due the relationship they have as both being IBM services.
Ok, now for the questions :p
First, since Cloudant was added to my app as a "service" it was generically provisioned and hence the username/pass/etc were generated. I assume I can also simply create my own separate Cloudant account and put an all of its settings into my Bluemix app manually. So, if I was to do that, to separately link up a separate Cloudantdb to my Bluemix app, would it be slightly slower or have any other negatives? I'm asking because maybe when it's auto-provisioned (and all done together), maybe it is configured in a way with few network hops/firewalls are skipped between the connections. Remember my initial motivation for trying out Bluemix was due to its relationship with Cloudant.
Second, if I decided to just stick with the auto-provisioned Cloudant db, how can I change the username? I've been playing with the interface and don't see that option anywhere. If I can or can't, I assume that I should be able to point my separate Heroku app to it using the same credentials Bluemix uses and it should work the same (as a separate db, just like I do with my single Mongolab and various PAAS providers).
Thanks for the info!

You can surely create your own separate Cloudant account, and then enter all of its settings into your Bluemix app manually. The connection speed would depend on your choice of data center locations (SoftLayer, Rackspace or Azure) when you created your Cloudant account. If you choose a SoftLayer data center, the speed would be faster than if you have chosen Rackspace or Azure due to the high-speed private network between all the SoftLayer data centers.
I'm not aware of a way to change usernames after it has been provisioned. You should be able to use those same credentials to point your Heroku app to.
I'm trying to create a back-end in which I can have many users communicate with each other amongst an iPhone app I'm creating. I've tried working with Core Data, Google App Engine, Google Cloud Storage, and Amazon Web Services (RDS & Elastic Beanstalk). Unfortunately, after weeks of trying to get any of this working, none of it will!
I've been trying to get in touch with someone who would know how startups (when they were little) like Instagram, Path, and Pinterest have managed to do this. But everyone out there seems to despise this stuff as much as I'm growing to...
I would love for someone to simply map out EXACTLY how I need to create a back-end database that I can save and query data to and from that many users can see. That means that just SQLite, Core Data, or Parse by itself isn't going to work here!
A tutorial of some kind would be incredible.
First off, technologies like CoreData and sqlite are typically local device storage. Local device storage is not going to get you shared cloud storage.
Parse.com is a fast way for devices to access cloud storage and get going fast. Especially useful for games and other mobile apps to access cloud data via an app id and app key. It's simple storage to avoid creating your own backend if it fills all your needs and requirements.
When you get to a multi-tenant cloud backend where you roll your own services and multiple devices accessing your cloud application you need to look into exposing your web API. Exposing RESTful API over http is great for devices and web clients. Exposing the data as JSON is especially conventient for the web and easily consumed by devices.
Those web service end points in the cloud access some sort of backend storage which is optimized for concurrent access by mutliple clients. This is typically a SQL backend like MySQL, SQLServer etc... or a NoSQL solution like mongodb, couchDB, etc...
Some front end web api technologies to look into:
ASP.net web api
Ruby on Rails
Node.js
etc...
Some back end storage technologies to look into:
SQL: MySQL, SQLServer/Azure SQL, Oracle
NoSQL: MongoDb, CouchDb, Amazon S3 simple storage, etc...
If the data is used by many many multi-tenant clients, the backends can scaled up (larger and larger) or get sharded. Sharding is where the data for multiple users is split into many databases or datastores with some sort of lookup algorithm for requests to find where that users data is stored. The front end web api servers abstract the backend storage.
Finally, you'll end up needing some sort of caching/fast lookup technology (if you're successful :):
Redis: fast in memory storage over sockets
memcached: facebook uses - simple key value in memory caching across many front end servers.
Your question is an open ended up broad question so start by googling many of these terms and technologies.
Each of these links will have resources and tutorials. Get a cloud VM, play with each and decide which fits your needs best. There is no one size fits all solution.

I'm new in iOS development, and I faced an issue with amazon.
I wanna gain information about amazon products with amazon web servises. I wanna enter the keyword and get information about proper products.
I looked at http://aws.amazon.com/mobile/ and saw that I should register. During the registration Amazon asked me about my Visa card information and then tried to withdraw 1 dollar.
The questions are:
Should I pay for amazon web services
Is it compulsory to register or I can just download Amazon sdk from http://aws.amazon.com/sdkforios/
Can you give some Amazon sdk code examples?
AWS is paid service. So, it's not a matter whether you should or not pay for using AWS. You MUST pay for the capacity you have used.
The pricing differs between the various services and is typically listed in http://aws.amazon.com/<service name>/pricing/. Here are couple of examples - EC2, S3.
Note that for some of the services there is a free tier for about a year, as long as you stay under certain amount of usage. So, while you WILL get a bill every month, that bill might be for $0.
More about the AWS Free Usage Tier.
You can download the client SDKs freely and write code against it. However, to actually run it against AWS, you will need AWS Access Key ID and Secret Access Key, so that AWS servers can authenticate the requests from your application (and incidentally also bil you properly for your usage).
You should start with the Getting Started with the AWS SDK for iOS and the AWS SDK for iOS FAQs. The SDK also contains bunch of sample apps into the <SDK install folder>/samples folder.
Update:
Ah, you want to search the Amazon catalog? That's different from AWS. AWS is intended to provide you access to computing resources (storage, CPU, load balancing, and so on) for your own services. For your scenario you need to use the Amazon Affiliate Program Product Advertising API.
While that API does share credentials with AWS (it uses the AWS Access Key ID and Secret Key), it most likely is free (but double check to be sure), as amazon will be making money on any product your users buy.
Also, the Product Advertising API does not have client SDKs (as far as I know), so you will have to deal with making the HTTP requests yourself. The API supports both REST and SOAP, so you can choose your own poison. There's also bunch of samples for both server and client apps, in PHP, C#, Java, Node.js, Ruby, and so on.
AWS is great! Its totally worth the price. So you can download the AWS iOS SDK and integrate it into your project; however, before it will work you need to signup. I would give you some examples but I don't fully understand what you're asking. The AWS iOS SDK has tons of code samples in it. If you want, you can comment on this post what you want to use AWS for and then I can help you come up with the code to achieve it :) I hope you have fun with iOS Development, its great :)
Good Luck!
Are you maybe confusing Amazon web services with a request API? You said:
I want to enter the keywork "iphone" and get some iphone products on amazon with its description and price
That is what an amazon web API would do (from this question, I understand there is maybe no such thing for Amazon?). AWS is a cloud service where you can run your programs and pay according to the resources you use. Think of that as a web host.
All in all, AWS is not directly related to Amazon content, if I understood correctly this is not what you want.
Yes of course you have to pay.
You can download it without registration, but you have to register to use it.
There is Documentation in AWS SDK for iOS.
