|
|
|
## Cloud Computing
|
|
|
|
|
|
|
|
|
|
Basicamente es el uso de servicio como servidores, almacenamiento, redes, bases
|
|
|
|
|
de datos y otros recursos computacionales a través de internet.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

### Tipos de Nube
|
|
|
|
|
|
|
|
|
|
- Nube Publica
|
|
|
|
|
- Nube Privada
|
|
|
|
|
- Nube Híbrida
|
|
|
|
|
|
|
|
|
|
### Tipos de servicios en la Nube
|
|
|
|
|
|
|
|
|
|
- **IaaS** Infrastructure as a Service
|
|
|
|
|
|
|
|
|
|
El tipo más común de servicio en la Nube.
|
|
|
|
|
Bajo laaS, el proveedor de la Nube proporciona la infraestructura de TI, como
|
|
|
|
|
servidores, almacenamiento y redes, y se paga de acuerdo al uso.
|
|
|
|
|
La mayoría de los recursos de TI ofrecidos en el modelo IaaS no están
|
|
|
|
|
pre-configurados, lo que significa que el consumidor tiene un alto grado de
|
|
|
|
|
control sobre el entorno en la Nube. Él es quien debe configurar y mantener
|
|
|
|
|
cualquier software que desee ejecutar sobre la infraestructura provista.
|
|
|
|
|
|
|
|
|
|
El IaaS ganó fuerza significativa en los últimos años, especialmente con
|
|
|
|
|
startups y divisiones independientes de empresas más grandes que tuvieran un
|
|
|
|
|
crecimiento rápido y busquen construir sus propias aplicaciones esenciales
|
|
|
|
|
para el negocio, pero evitan la inversión y el mantenimiento que la
|
|
|
|
|
infraestructura requerirá.
|
|
|
|
|
|
|
|
|
|
Además se trata de empresas que muchas veces buscan escalabilidad inmediata,
|
|
|
|
|
ya que por el rápido crecimiento, necesitan estar preparados para lidiar con
|
|
|
|
|
un volumen cada vez mayor de trabajo. Con IaaS existe la posibilidad de
|
|
|
|
|
comprar un nuevo servidor virtual, instalarlo por cuenta propia y obtener esa
|
|
|
|
|
capacidad adicional en una porción de tiempo mas pequeño.
|
|
|
|
|
|
|
|
|
|
- **PaaS** Platform as a Service
|
|
|
|
|
|
|
|
|
|
PaaS (que significa plataforma como servicio) es un modelo informático en el
|
|
|
|
|
cual el proveedor de la Nube te asigna, configura y gestiona toda la
|
|
|
|
|
infraestructura informática, como servidores, redes como en IaaS, así como
|
|
|
|
|
sistemas operativos, bases de datos, herramientas de desarrollo y
|
|
|
|
|
administración de empresas.
|
|
|
|
|
|
|
|
|
|
En otras palabras, en PaaS toda la configuración de la base de datos, la
|
|
|
|
|
seguridad y las replicaciones son realizadas por el proveedor con pocos
|
|
|
|
|
márgenes de configuración, diferente de IaaS, donde las principales
|
|
|
|
|
configuraciones son hechas por el desarrollador, lo que hace que PaaS sea
|
|
|
|
|
más costosa que IaaS.
|
|
|
|
|
|
|
|
|
|
PaaS es un ambiente de informático listo para su uso, una vez que los
|
|
|
|
|
recursos y servicios ya están implementados y configurados. Los servicios
|
|
|
|
|
informáticos PaaS incluyen aquellos que lo ayudan a desarrollar, probar y
|
|
|
|
|
entregar aplicaciones de software personalizadas.
|
|
|
|
|
|
|
|
|
|
Los desarrolladores pueden crear sus aplicaciones rápidamente y un proveedor
|
|
|
|
|
de la Nube configura y administra la infraestructura informática subyacente.
|
|
|
|
|
El consumidor puede reemplazar todo el ambiente informático local por el de
|
|
|
|
|
PaaS o usar PaaS para expandir su ambiente de TI y/o reducir costos con el
|
|
|
|
|
ambiente en la nube.
|
|
|
|
|
|
|
|
|
|
- **SaaS** Software as a Service
|
|
|
|
|
|
|
|
|
|
SaaS es como un proveedor de la Nube que ofrece aplicaciones de software bajo
|
|
|
|
|
demanda. En este modelo, el proveedor administra no solo la infraestructura
|
|
|
|
|
sino también las aplicaciones de software y los usuarios que se conectan a
|
|
|
|
|
la aplicación a través de internet.
|
|
|
|
|
|
|
|
|
|
El software se modela como un servicio de la Nube compartido y disponible
|
|
|
|
|
para los usuarios como un producto. Los consumidores de la Nube tienen el
|
|
|
|
|
control administrativo y de gestión limitado.
|
|
|
|
|
|
|
|
|
|
Un ejemplo bien conocido de SaaS es Spotify, que es un servicio de música de
|
|
|
|
|
streaming, podcast y video que fue lanzado en Octubre de 2008 en Estocolmo,
|
|
|
|
|
Suecia. Es el servicio de streaming más popular y mas usado en todo el mundo.
|
|
|
|
|
|
|
|
|
|
SaaS es esencialmente la entrega de aplicaciones directamente de la Nube para
|
|
|
|
|
usuarios individuales. El hardware que procesa los datos como así también el
|
|
|
|
|
sistema operativo y no le importará nada para los usuarios finales. que
|
|
|
|
|
acceden a estas aplicaciones a través de una plataforma como Chrome, Firefox,
|
|
|
|
|
Safari, Google Play o Apple Store.
|
|
|
|
|
|
|
|
|
|
Organizaciones de todos los tamaños han migrado a SaaS. ¿Y por que no?, Por
|
|
|
|
|
lo tanto no necesitan invertir en mucho hardware y sistemas operativos caros.
|
|
|
|
|
Además, no tienen que pagar un equipo de TI para mantener la infraestructura
|
|
|
|
|
o solucionar problemas de las aplicaciones.
|
|
|
|
|
|
|
|
|
|
El proveedor de SaaS ofrece todo eso. En caso de no utilizar un proveedor de
|
|
|
|
|
SaaS, las empresas necesitan comprar una licencia perpetua para ejecutar una
|
|
|
|
|
aplicación de software en sus sistemas.
|

### What is Cloud Shell?
|
|
|
|
|
|
|
|
|
|
```txt
|
|
|
|
|
Cloud Shell is a free web browser-based terminal accessible from the Oracle Cloud
|
|
|
|
|
Console that is pre-installed with a set of useful tools. Each user is provided a
|
|
|
|
|
5 GB home directory which provides persistent storage for your files.
|
|
|
|
|
|
|
|
|
|
Cloud Shell allows you to perform tasks including:
|
|
|
|
|
|
|
|
|
|
* Writing Linux scripts for managing your Oracle Cloud Infrastructure (OCI)
|
|
|
|
|
environment
|
|
|
|
|
* Developing or running applications built using the OCI SDKs
|
|
|
|
|
* Building and running docker containers
|
|
|
|
|
* Managing your Oracle Cloud Infrastructure (OCI) Functions
|
|
|
|
|
* Accessing public and private resources including:
|
|
|
|
|
* Running OCI CLI commands to manage your resources
|
|
|
|
|
* Accessing your Oracle Container Engine for Kubernetes clusters
|
|
|
|
|
* Accessing your compute instances using ssh
|
|
|
|
|
* Managing your Autonomous Databases
|
|
|
|
|
|
|
|
|
|
Your persistent home directory allows you to store scripts and files in your
|
|
|
|
|
Cloud Shell which will be retained for your next session even if you exit or
|
|
|
|
|
restart Cloud Shell. Those files live in your Cloud Shell environment and can
|
|
|
|
|
not be accessed by other users.
|
|
|
|
|
|
|
|
|
|
The OCI CLI is pre-configured to run as you with all of the policies and
|
|
|
|
|
privileges that have been assigned to you by your Administrator. No additional
|
|
|
|
|
set up is required to use it.
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|

### Using the OCI Command Line Interface (CLI)
|
|
|
|
|
|
|
|
|
|
```txt
|
|
|
|
|
Included in Cloud Shell is a current version of the OCI CLI. The CLI is a
|
|
|
|
|
small-footprint tool that you can use on its own or with the Console to complete
|
|
|
|
|
Oracle Cloud Infrastructure
|
|
|
|
|
tasks. The CLI provides the same core functionality as the Console, plus
|
|
|
|
|
additional commands. Some of these, such as the ability to write and run scripts,
|
|
|
|
|
extend Console functionality.
|
|
|
|
|
|
|
|
|
|
Cloud Shell updates the version of the OCI CLI on a regular basis. This means you
|
|
|
|
|
are always using the latest version of our tools. We also automatically configure
|
|
|
|
|
your credentials when
|
|
|
|
|
you launch Cloud Shell so no further setup is required to use the OCI CLI in
|
|
|
|
|
Cloud Shell. Authentication happens automatically.
|
|
|
|
|
|
|
|
|
|
Hit return to run the oci command oci iam availability-domain list :
|
|
|
|
|
|
|
|
|
|
$ oci iam availability-domain list
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Using the OCI CLI in Interactive Mode
|
|
|
|
|
|
|
|
|
|
```txt
|
|
|
|
|
The CLI also has an interactive mode that simplifies your OCI CLI user experience
|
|
|
|
|
with several new features, including command and parameter suggestions,
|
|
|
|
|
auto-completion, and command reference information.
|
|
|
|
|
|
|
|
|
|
In interactive mode, suggestions will be made as you navigate the command line.
|
|
|
|
|
For example, it can help find the right arguments for a command, and fill in
|
|
|
|
|
ocids by allowing you to search based on display names.
|
|
|
|
|
|
|
|
|
|
An example of a command you can run is oci iam availablity-domain list.
|
|
|
|
|
|
|
|
|
|
To try that now, and go into interactive mode, type oci -i and then hit Return.
|
|
|
|
|
|
|
|
|
|
And then try the following:
|
|
|
|
|
|
|
|
|
|
1. Type in iam and then a space. The CLI will give you a list of choices.
|
|
|
|
|
2. Type avail and then hit tab to autocomplete the command
|
|
|
|
|
3. Type a space and then list and then hit return to finish the command
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Type oci -i to go into interactive mode:
|
|
|
|
|
$ oci -i
|
|
|
|
|

### Using Docker
|
|
|
|
|
|
|
|
|
|
```txt
|
|
|
|
|
You can use Docker from within Cloud Shell to develop software.
|
|
|
|
|
|
|
|
|
|
Hit return to docker run hello-world:
|
|
|
|
|
|
|
|
|
|
$ docker run hello-world
|
|
|
|
|
|
|
|
|
|
Hello from Docker!
|
|
|
|
|
This message shows that your installation appears to be working correctly.
|
|
|
|
|
|
|
|
|
|
To generate this message, Docker took the following steps:
|
|
|
|
|
1. The Docker client contacted the Docker daemon.
|
|
|
|
|
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
|
|
|
|
|
(amd64)
|
|
|
|
|
3. The Docker daemon created a new container from that image which runs the
|
|
|
|
|
executable that produces the output you are currently reading.
|
|
|
|
|
4. The Docker daemon streamed that output to the Docker client, which sent it
|
|
|
|
|
to your terminal.
|
|
|
|
|
|
|
|
|
|
To try something more ambitious, you can run an Ubuntu container with:
|
|
|
|
|
$ docker run -it ubuntu bash
|
|
|
|
|
|
|
|
|
|
Share images, automate workflows, and more with a free Docker ID:

|
|
The OCI Software Development Kits (SDKs) allow you to build and deploy apps that
|
|
|
|
|
integrate with Oracle Cloud Infrastructure services. Each SDK provides the tools
|
|
|
|
|
you need to develop an app, including code samples and documentation to create,
|
|
|
|
|
test, and troubleshoot. In addition, if you want to contribute to the development
|
|
|
|
|
of the SDKs, they are all open source and available on GitHub.
|
|
|
|
|
|
|
|
|
|
Cloud Shell installs and updates the version of the OCI SDKs on a regular basis.
|
|
|
|
|
This means you are always using recent versions of our tools. We also
|
|
|
|
|
automatically configure your credentials when you launch the Cloud Shell so you
|
|
|
|
|
do not have to set up keys if you use the default authentication provider.
|
|
|
|
|
|
|
|
|
|
To get up and running quickly, you can look at the SDK Cloud Shell Quick Starts
|
|
|
|
|
for each of the languages:
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
You can also find source and examples on GitHub for the SDKs.

### Code Editor
|
|
|
|
|
|
|
|
|
|
```txt
|
|
|
|
|
Cloud Shell integrates seamlessly with the OCI Code Editor, allowing you to edit
|
|
|
|
|
code, modify scripts, and update service workflows directly from the OCI Console.
|
|
|
|
|
|
|
|
|
|
The Code Editor lets you browse, view, and edit files in your Cloud Shell home
|
|
|
|
|
directory and provides a convenient way to perform common code updates for
|
|
|
|
|
various services, including creating and deploying Functions, editing Terraform
|
|
|
|
|
configurations used with Resource Manager stacks, and creating and editing an API.
|
|
|
|
|
It offers the following capabilities that enhance your productivity:
|
|
|
|
|
|
|
|
|
|
* Built-in integration with OCI services, including Functions,
|
|
|
|
|
Resource Manager, and Data Science
|
|
|
|
|
* Access to Cloud Shell and 30+ cloud-based tools
|
|
|
|
|
* Git integration and workspace management
|
|
|
|
|
* Rich language support
|
|
|
|
|
* Session continuity
|
|
|
|
|
* Personalized user experience
|
|
|
|
|
|
|
|
|
|
You can access this from the View menu in the Cloud Shell window or directly from
|
|
|
|
|
the Developer Tools icon in the Console header.
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Configuring Java Versions
|
|
|
|
|
|
|
|
|
|
```txt
|
|
|
|
|
You can use csruntimectl to configure your version of Java.
|
|
|
|
|
|
|
|
|
|
To see the set of available Java versions see `csruntimectl java list`.
|
|
|
|
|
Your current JDK is indicated by an *.
|
|
|
|
|
Hit return to list the JDKs available on this system:
|
|
|
|
|
|
|
|
|
|
$ csruntimectl java list
|
|
|
|
|
graalvmeejdk-17 /usr/lib64/graalvm/graalvm22-ee-java17
|
|
|
|
|
* oraclejdk-11 /usr/java/jdk-11.0.17
|
|
|
|
|
oraclejdk-1.8 /usr/lib/jvm/jdk-1.8-oracle-x64
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
You can then set the JDK version by using the command
|
|
|
|
|
`csruntimectl java set <version from above>`
|
|
|
|
|
|
|
|
|
|
Hit return to show your current JAVA_HOME:
|
|
|
|
|
|
|
|
|
|
$ echo $JAVA_HOME
|
|
|
|
|
/usr/lib64/graalvm/graalvm22-ee-java17
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Transferring Files to and from your Cloud Shell
|
|
|
|
|
|
|
|
|
|
```txt
|
|
|
|
|
In addition to creating new files and scripts, you can upload files to and
|
|
|
|
|
download files from your Cloud Shell.
|
|
|
|
|
|
|
|
|
|
Under the tools (aka gear) icon on the top right corner of the Cloud Shell header
|
|
|
|
|
are three options related to File Upload/Download:
|
|
|
|
|
|
|
|
|
|
* Download - allows you to transfer files from your Cloud Shell to your local
|
|
|
|
|
computer
|
|
|
|
|
* Upload - allows you to transfer files from to Cloud Shell from your local
|
|
|
|
|
computer
|
|
|
|
|
* File Transfers - allows you to view active and completed Uploads and
|
|
|
|
|
Downloads
|
|
|
|
|
|
|
|
|
|
To Upload files, you can either drag an drop files into the upload dialog (or
|
|
|
|
|
even directly into Cloud Shell) or use the file selection dialog to select
|
|
|
|
|
individual files.
|
|
|
|
|
|
|
|
|
|
Try dragging a file into the Cloud Shell window to try to upload now.
|
|
|
|
|
|
|
|
|
|
To Download files, you will have to enter the path starting at your home
|
|
|
|
|
directory in the dialog box. For example, if your file was in ~/temp/myfile you
|
|
|
|
|
would enter temp/myfile.
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Understanding Regions
|
|
|
|
|
|
|
|
|
|
```txt
|
|
|
|
|
Your Cloud Shell host (and your home directory) live in the Home Region for your
|
|
|
|
|
tenancy regardless of what region is selected in the region pull-down menu in the
|
|
|
|
|
top right corner of the console. This allows your home directory to be available
|
|
|
|
|
no matter what region you are operating in.
|
|
|
|
|
|
|
|
|
|
Your current region (the region you have selected in the pull-down) is used when
|
|
|
|
|
accessing tenancy resources using the OCI Command Line Interface (CLI) or the OCI
|
|
|
|
|
Software Development Kits (SDKs).
|
|
|
|
|
|
|
|
|
|
In the current Cloud Shell Session:
|
|
|
|
|
|
|
|
|
|
* Your Home region is us-phoenix-1
|
|
|
|
|
* Your Console selected region is us-phoenix-1
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Note: The region used by the SDKs/CLIs is "sticky" based on what was selected in
|
|
|
|
|
the console when your Cloud Shell was opened and persists as long as the session
|
|
|
|
|
exists. You can identify what region is active by looking at the Cloud Shell
|
|
|
|
|
prompt. It will look like:
|
|
|
|
|
|
|
|
|
|
<username>@cloudshell:<directory> (<region>)
|
|
|
|
|
|
|
|
|
|
If you want to change your region for the CLI/SDK:
|
|
|
|
|
|
|
|
|
|
* Select a new region in the Console region pull-down menu, near the top of
|
|
|
|
|
the Console.
|
|
|
|
|
* Close and reopen your terminal.
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Understanding Network Access from your Cloud Shell
|
|
|
|
|
|
|
|
|
|
```txt
|
|
|
|
|
By default, your Cloud Shell uses our Public Network which is provisioned with
|
|
|
|
|
both a Service Gateway and additionally has egress to the internet. From your
|
|
|
|
|
Cloud Shell Public Network connection, you can run OCI CLI commands to access
|
|
|
|
|
tenancy resources and also reach public resources. The access to public resources
|
|
|
|
|
allows you to perform tasks like using ssh to access public instances, managing
|
|
|
|
|
public OKE Clusters and pulling from public git repositories.
|
|
|
|
|
|
|
|
|
|
If you would like to access resources which do not have a public IP, you can
|
|
|
|
|
instead use a Private Network Connection. Using Private Network Access, you can
|
|
|
|
|
connect to a subnet (assuming your administrator has granted you permission) that
|
|
|
|
|
lives in your home region.
|
|
|
|
|
|
|
|
|
|

https://docs.oracle.com/en-us/iaas/Content/API/Concepts/cloudshellintro.htm#Cloud_Shell_Private_Access
|
|
|
|
|
|
|
|
|
|
Note: No ingress to your Cloud Shell Hosts (in either public or private networks)
|
|
|
|
|
is supported.
|
|
|
|
|
```
|
|
|
|
|
|

|
|
