From 0fd7b3116fbace7deb8202d1849cece7146462a9 Mon Sep 17 00:00:00 2001 From: Fabian Mastenbroek Date: Thu, 17 Jun 2021 14:15:45 +0200 Subject: faas: Rename opendc-serverless to opendc-faas This change renames the opendc-serverless module to opendc-faas to better distinguish between the two terms (Serverless and FaaS) and be clearer about the intent of the module. The opendc-faas module holds the code for the FaaS platform on top of OpenDC. Although this is one approach of doing serverless, serverless can also entail other services that will not be covered by this module. --- .../main/kotlin/org/opendc/faas/api/FaaSClient.kt | 74 ++++++++++++++++++++++ .../kotlin/org/opendc/faas/api/FaaSFunction.kt | 70 ++++++++++++++++++++ 2 files changed, 144 insertions(+) create mode 100644 opendc-faas/opendc-faas-api/src/main/kotlin/org/opendc/faas/api/FaaSClient.kt create mode 100644 opendc-faas/opendc-faas-api/src/main/kotlin/org/opendc/faas/api/FaaSFunction.kt (limited to 'opendc-faas/opendc-faas-api/src') diff --git a/opendc-faas/opendc-faas-api/src/main/kotlin/org/opendc/faas/api/FaaSClient.kt b/opendc-faas/opendc-faas-api/src/main/kotlin/org/opendc/faas/api/FaaSClient.kt new file mode 100644 index 00000000..ebda4f90 --- /dev/null +++ b/opendc-faas/opendc-faas-api/src/main/kotlin/org/opendc/faas/api/FaaSClient.kt @@ -0,0 +1,74 @@ +/* + * Copyright (c) 2021 AtLarge Research + * + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in all + * copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
