0 Oracle Cloud Infrastructure Cloud Shell is VM that runs inside OCI -to be used for manipulating OCI resources using various means, including OCI CLI, Terraform and Ansible. We may want to be able to get files into Cloud Shell – scripts, source code, Infrastructure as Code and more. There are […]
0 0 Cloud Shell on Oracle Cloud Infrastructure is a versatile management and development environment to access and manage Oracle Cloud Infrastructure resources. Cloud Shell comes with many tools and runtime out of the box (or rather inside the box) including OCI CLI, Java and SQL*Plus. However, the Oracle SQL Developer Command […]
0 0 Objective of this article: connect SQL*Plus in Cloud Shell to an Autonomous Database instance (in a free tier – in the same or a different cloud tenancy) The starting situation: I have an autonomous database instance running somewhere in Oracle Cloud Infrastructure. I have Cloud Shell as a versatile management […]
0 0 This article tells you how to access the Kubernetes Dashboard on top of an Oracle Cloud Infrastructure OKE Cluster Instance from a browser – without locally installing kubectl. This trick uses OCI Cloud Shell to run kubectl to proxy to the dashboard application running inside the K8S Cluster and it […]
0 0 Cloud Shell in Oracle Cloud Infrastructure is a free browser based command line tool for various types of interactions within your OCI Tenancy. When you start Cloud Shell, a command line is opened in your browser. You are in a Linux environment (Oracle Linux 7.7) that runs within the OCI […]
0 0 This morning I discovered a new entry in the menu on my Oracle Cloud Infrastructure Tenancy (on Ashburn, USA): the NoSQL Database service had been added overnight. The service offers a key-(schema-less) document store. It also supports ACID transactions, SQL on JSON documents, joins across tables, structured tables and if […]
0 0 Resources in Oracle Cloud Infrastructure can be managed through the console – the browser based UI. That works great but requires manual steps – no automation – that take time and easily go wrong (and become extremely boring over time). Additionally, it is a rather individualistic way of working that […]
0 0 Oracle provides several services as ‘always free’. In contrast to Azure and Amazon, these include compute instances which remain ‘forever’ free to use. Although there are some limitations on CPU, disk, network resources, these instances are ideal to use as a remote SSH server and with a little effort a […]
0 0 In earlier articles, I have discussed features in Oracle Cloud Infrastructure for monitoring metrics published by virtually all OCI services. These metrics get published when functions are invoked, files are written, the API Gateway handles a request, events are published, a user is created and a network transfers a packet. […]
0 0 In this article, I want to show how you can very quickly run a Docker container for free on Oracle Cloud Infrastructure – using a VM in the Always Free Tier of OCI. As an example, I will run an NGINX container image and access that from a client over […]
0 0 Oracle Cloud Infrastructure gathers metrics from all OCI resources. These metrics can be visualized and analyzed with the Metrics Explorer. And Alarms can be defined with rules evaluating the metrics that publish to a Notification Topic to signal a situation of interest. Subscriptions can be defined on these Notification Topics, […]
0 0 We call them serverless and we consider them stateless. Functions on Oracle Cloud Infrastructure (and on other cloud platforms). Of course they are neither. They run on servers. And they can carry some state, though largely opportunistic and not reliably. Functions on OCI run inside a container. The container is […]
0 0 In a recent article, I described how serverless Functions on Oracle Cloud Infrastructure can invoke each other: synchronously and asynchronously. Although asynchronous calls are the desired state, such calls currently are possible only with quite a bit of hassle – using a Stream for queuing asynchronous requests and a Listener […]
0 0 OCI allows for cloud native application development, using facilities such as serverless functions, a light weight API gateway, a streaming service for asynchronous communication based on event messaging and built-in monitoring. In previous articles, I have gone over several aspects of serverless functions and API Gateways to create and expose […]
0 0 Execution of scheduled jobs based on a time schedule is a frequent requirement. Jobs on Oracle Cloud Infrastructure are often implemented using cloud native, serverless Functions – that can be exposed through (public) HTTP endpoints on an API Gateway. I recently published an article describing how execution of functions can […]
0 0 Oracle Cloud Infrastructure offers the Streaming service. This service is easily described as a Kafka-like fully managed event platform for high volume streams of data that can be processed in real or delayed time in a durable, reliable way. And from the documentation: “Streaming can be used for messaging, ingesting […]
0 0 Fire and forget messaging is a powerful concept. Asynchronous, decoupled communication is key to scalability and independence of services. Oracle Cloud provides a pub/sub solution called Oracle Messaging Cloud Service. This is an HTTP based publish and subscribe mechanism for asynchronous communication – based on persistent messages and durable subscriptions. […]
0 0 The objective for this article is to show you how to get to the point where two routes are available on an API Gateway on Oracle Cloud Infrastructure that allow easy writing to a file on Object Storage and easy retrieval of such as file. Writing files is obviously useful […]
0 0 This article demonstrates a set up that is probably mainly of theoretical interest or maybe useful in demonstrations. I describe how we can invoke an OCI serverless Function through the API Gateway and ask the serverless function for values that are read from a [read only] cache. This cache is […]
0 0 The objective in this article: create a simple Authorizer Function that checks the Client Secret passed in API calls and allows and denies requests based on whether the correct Client Secret is included. The Authorizer Function does a little more than simply accept or deny: in case of accept it […]
0 0 Oracle Cloud Infrastructure API Gateway makes it possible to expose OCI Functions on public endpoints that do not require complex signed HTTP requests. Any function that should be easily publicly accessible can be given such easy access. By creating an API Deployment on an API Gateway and associating a route […]
0 0 Functions on Oracle Cloud are an important element in any cloud native application architectures. Functions are typically small, well contained and fairly independent pieces of logic to carry out specific tasks. These tasks can be executed upon reception and handling of HTTP requests – a very common use case – […]
0 0 This article is fairly rough log of the steps I went through to get going on Oracle Cloud Serverless Functions. It is mainly intended to provide a note to myself, for future reference. However, my description could prove useful to you – the reader. My steps to get going are […]
0 0 The API Gateway service on Oracle Cloud Infrastructure went live very recently – read my overview article of what API Gateway entails. In brief: API Gateway is a reverse proxy that exposes HTTP endpoints on which external (or internal) clients can make requests. API Gateway can handle these requests: authorize, […]
0 0 Two days ago, the API Gateway service on Oracle Cloud Infrastructure went live – read the announcement. This is a crucial component for many applications and in many solution designs. This new API Gateway is a prime candidate for example for inclusion in our reference architecture for OCI based solution […]
0 0 Last week at AMIS we had the task of estimating costs of a proposed iPaaS solution for one of our customers that runs on a fully managed cloud. As AMIS is mainly an Oracle partner we looked at how competitive we could make the pricing of the solution using Oracle […]
