API management is the process of creating and publishing web application programming interfaces (APIs), enforcing their usage policies, controlling access, nurturing the subscriber community, collecting and analyzing usage statistics, and reporting on performance. API Management components provide mechanisms and tools to support developer and subscriber communities.[1]

Components

While solutions vary, components that provide the following functions are typically found in API management products:

Gateway

A server that acts as an API front-end, receives API requests, enforces throttling and security policies, passes requests to the back-end service and then passes the response back to the requester.[2] A gateway often includes a transformation engine to orchestrate and modify the requests and responses on the fly. A gateway can also provide functions such as collecting analytics data and providing caching. The gateway can provide the functionality to support authentication, authorization, security, audit and regulatory compliance.[3] Gateways can be implemented using technologies like Nginx or HAProxy.

Publishing tools

A collection of tools that API providers use to define APIs, for instance using the OpenAPI or RAML specifications, generate API documentation, govern API usage through access and usage policies for APIs, test and debug the execution of API, including security testing and automated generation of tests and test suites, deploy APIs into production, staging, and quality assurance environments, and coordinate the overall API lifecycle.

Developer portal/API store

A community site, typically branded by an API provider, that can encapsulate for API users in a single convenient source information and functionality including documentation, tutorials, sample code, software development kits, an interactive API console and sandbox to trial APIs, the ability to subscribe to the APIs and manage subscription keys such as OAuth2 Client ID and Client Secret, and obtain support from the API provider and user and community.

Reporting and analytics

Functionality to monitor API usage and load (overall hits, completed transactions, number of data objects returned, amount of compute time and other internal resources consumed, the volume of data transferred). This can include real-time monitoring of the API with alerts being raised directly or via a higher-level network management system, for instance, if the load on an API has become too great, as well as functionality to analyze historical data, such as transaction logs, to detect usage trends. Functionality can also be provided to create synthetic transactions that can be used to test the performance and behavior of API endpoints. The information gathered by the reporting and analytics functionality can be used by the API provider to optimize the API offering within an organization's overall continuous improvement process and for defining software Service-Level Agreements for APIs.

Monetization

Functionality to support charging for access to commercial APIs. This functionality can include support for setting up pricing rules, based on usage, load and functionality, issuing invoices and collecting payments including multiple types of credit card payments.

Market size

A number of industry analysts have observed that the size of the market for API management solutions has been growing rapidly since the early 2010s. Gartner estimated the size of the market for API management to be $70 million in 2013 and to be growing at 40% a year.[4] According to Forrester Research, in the US alone, annual spend on API management was $140 million in 2014, expected to grow to $660 million by 2020 with total global sales are predicted to exceed a billion dollars by that year. The most recent market analysis, conducted by KBV Research in 2019, predicted continuing CAGR of 28.4% taking the total market value to $6.2billion by 2024[5][6][7]


Option sans passerelle sur site, uniquement avec une passerelle sur le cloud :

    • Avantages :**

1. **Évolutivité :** L'architecture basée sur le cloud permet une mise à l'échelle plus facile en fonction des besoins, sans nécessiter de matériel sur site.

2. **Maintenance simplifiée :** En l'absence de passerelle sur site, la maintenance et les mises à jour logicielles peuvent être gérées de manière centralisée dans le cloud, réduisant ainsi la complexité opérationnelle.

3. **Coûts réduits :** Éliminer la nécessité d'avoir une infrastructure sur site peut entraîner des économies significatives en termes d'investissements initiaux et de coûts de maintenance.

4. **Accessibilité distante :** La passerelle basée sur le cloud permet un accès à distance pour la gestion et la surveillance, facilitant la gestion décentralisée.

    • Enjeux :**

1. **Dépendance à Internet :** La fiabilité de la solution dépend fortement de la disponibilité d'une connexion Internet stable.

2. **Latence :** Les performances peuvent être affectées par la latence réseau entre les dispositifs locaux et la passerelle basée sur le cloud.

3. **Confidentialité des données :** Les données transitent par Internet, ce qui nécessite une attention particulière à la sécurité pour garantir la confidentialité des informations.

    • Risques :**

1. **Indisponibilité du Cloud :** En cas de panne du service cloud, l'ensemble du système pourrait être hors service.

2. **Sécurité du Cloud :** Les risques de sécurité liés à l'utilisation d'une passerelle basée sur le cloud, y compris les attaques potentielles sur les données stockées en ligne.

    • Conditions de mise en place :**

1. **Connectivité Internet robuste :** Assurer une connexion Internet fiable et redondante pour garantir la disponibilité du système.

2. **Politiques de sécurité strictes :** Mettre en place des politiques de sécurité strictes pour protéger les données transitant par le cloud.

3. **Formation du personnel :** Fournir une formation adéquate aux utilisateurs et au personnel de maintenance pour optimiser l'utilisation de la solution basée sur le cloud.

    • Évaluation des travaux :**

1. **Performances :** Évaluer la latence, la vitesse de traitement et la réactivité de la solution dans des conditions réelles.

2. **Sécurité :** Réaliser des audits de sécurité pour identifier et corriger les vulnérabilités potentielles.

3. **Coûts :** Comparer les coûts initiaux et opérationnels avec les avantages prévus pour s'assurer que la solution est économiquement viable.
